Similar to the five easy steps for creating world peace.
Step 1: Cure every disease known to man
Stop popping prescription drugs like they are candy and only use drugs in emergency situations for a short period of time if no alternative is present.
Eliminate 'money' from the industry and actually implement proper science and scientific methods towards CURING people and not merely treating symptoms with drugs that can (and probably will) produce high toxicity in peoples bodies ending in damage of internal organs and nasty side-effects (one of which can easily be death - oh wait, that already happens).
Step 2: Resolve every international/intranational conflict in the wold
Eliminate a monetary based economy (communism btw HAD money) which is a primary source of conflict.
Instead focusing on our differences, focus on common grounds and encourage global cooperation with competition being limited to games only.
Step 3: Eliminate poverty
Step 4: Eliminate crime
Step 5: Eliminate all forms of prejudice and discrimination everywhere.
In order to do that, people need to be educated that there are alternatives out there (and there have been for some time now).
And for 'eliminating all forms of prejudice and discrimination everywhere' - how about we try focusing on what we have in common, global cooperation, sharing, giving, helping, etc. and actively encouraging those aspects?
New systems (or system) will probably require different levels of thinking and numerous forms of 'outdated traditions' (although probably not all of them) will have to be discarded by many if we are to move forward.
Encouragement of tolerance of others should probably be a priority in such a case along with the premise of 'live and let live' (to name a few), along with education, etc.
Money and financial inequality are actually a major factor in regards to poverty and crime (not to mention greed and a lot of other problems we are facing today).
Eliminate monetary based economy by slowly replacing it with a resource based economy where there is no notion of 'value', 'money', 'private ownership' or any ridiculous forms of governments or 'isms' that have always had 'money' or some type of currency as a common medium.
Distribution of resources should be fully automated in this case and equally available to all humans on the globe according to their actual needs (and not the wasteful usage of resources to create useless things based on advertisements that make people buy things for the sake of generating profits) - to be done in an efficient/intelligent way that doesn't do damage to the environment we live in.
Its possible though, and no, its not 'perfect' (nor is it 'utopia)... plus it would be sustainable in the long run and provide a high quality of life for everyone because of the following:
Recycling technologies for converting trash into alternative energy or usable resources existed since the early 20th century (before 1920).
By then, automation was already incorporated on a relatively large scale industry-wise and could have been used to replace majority of menial based work - it is something we do today in large quantities (though it could be done on a global scale).
We also had the ability for decades to recycle radioactive waste into plutonium (which could be used as an energy source) - but in a monetary based system, it is cheaper to simply dump it into the ground and pollute the environment and an 'excuse' was made that it allows for proliferation of new weapons - which is absurd because we already have weapons capable of decimating Humanity as we know it several times over.
The US alone is wasting ridiculously large amounts of food that could be used to feed starving nations (Europe and other developed countries do the same), which doesn't include the ability to grow crops in deserts, or out capabilities of creating clean water via technological means, or ability to desalinate water.
Energy issues are a problem based in common sense and largely hampered by energy and oil companies, not the actual technology or resources needed for execution.
We had the technology since 1950's in case of solar power (despite their low efficiency - which would have provided MORE than enough power for a single home and the excess could have been shuffled to others), and in case of Geothermal power, we could have used it since the early 1930's.
That of course, doesn't take into account tidal, wind and other sources of power which by today were augmented since their initial inceptions.
And those are but a few suggestions.
It's as easy as bending a spoon with your thoughts.
Not necessarily 'easy' due to the monetary system we live in and the mentality majority are brought up to live by (which is usually the problem that prohibits people from taking into account other possibilities which are immediately discarded as 'impossible' - simply because they can't help themselves but think along those lines) - but it is possible.
In the end, if we want to make a better world, we can't do it by giving up without trying.
Options exist. A monetary based system inevitably incites greed and competition for resources which are SAID to be scarce and is based on 'survival of the fittest' (and such a system is outdated) - in reality, Earth is pretty abundant in resources and there would be enough for everyone IF THEY ARE DISTRIBUTED EQUALLY and INTELLIGENTLY - a monetary based approach and endless/wasteful consumption of resources will inevitably lead to exhaustion - by which time, it might be too late (and in the meantime will create more unemployment, starvation, homeless people, probably wars, etc.).
And whoever starts by saying that it would be 'impossible to alter human nature' ... for all accounts and purposes, its a learned behavior - you are a product of a system/society/culture you grew up in.
By that same token, a person that was brought up by amazons or barbarians would probably grow up to adopt the values of that particular culture.
Also... to those who ask 'why would people have an incentive to work' if all of their needs are met - the answer is simple: even today you have ample amount of people who work because they LIKE doing it (a lot of them are doing it on a voluntary basis even) - the thing would be that its a fundamentally different perspective on life.
Its not fantasy or science fiction regardless of how many would like it to be.
And I conclude with the premise that a lot of people might actually find a way to completely and utterly shoot this argument down because it is likely that to them it will inevitably seen as something that 'simply cannot work', or as 'fantasy' (that the world and people are too different, and that no economy can work if there is no central government or someone who runs the entire thing - given the computing power we have today [not taking into account the things we could have done over a decade to enhance it by a factor of up to 50 or more in both power/speed/efficiency if 'money' was never brought into account] it could been used by humans to program automation to such a level where it would be possible to use existing technology for ascertaining the amount of resources we have at our disposal for intelligent distribution of the said resources).
I also wonder... when was the last time humans at large asked themselves if we can do something from a resource/technological point of view, and not a monetary one.
Ah yes, during WW2 when the US was able to churn out over 90 000 planes per year (they didn't have the money or enough gold to make it happen - but they had enough resources/technology/manpower to pull it off).
Such a practice is only considered in times of war.
I'm sorry, but whenever I look at history and the problems people endured in a monetary based system (communism btw DID have money and there was also a notion of state, borders, etc.), I didn't think it was something that 'benefited' people or was 'the best system devised'.
Most of the systems previously attempted failed because they were perverted into something they were not - and all of them used money in some way.
Resource based economy doesn't have that - because its based on an entirely different premise.
Think what you will...
But if you are interested... google up Venus Project for details (and for the sake of this discussion - I already reached similar/same ideas before becoming acquainted with the Venus Project and RBE in general - as did many other people actually).
