In what way are the poor better off than 100 years ago?
The easy availability of food
Low Income Housing
Better health care (no dying of polio or smallpox anymore)
Even poor people today have cell phones and the internet, shoot even television, things that even the richest of the rich would never have dreamed of 100 years ago. Technology like that is available to everyone.
Life is quite simply better today than it was 100 years ago. You may think that life is shitty today, but it is remarkably less shitty than it was 100 years ago. Yes, we still have a ways to go with social reform, health care, education, and many other things, but Rome wasn't built in a day. You are lying to yourself if you think a poor person today has a worse quality of life than a poor person 100 years ago.
I had almost this exact same argument on another forum, except the time frame was 30 years. The question was "Is quality of life better today than it was 30 years ago". You can always tell the difference between a pessimist and an optimist when answering questions like these, because some people refuse to see that despite the walls we still have left to climb/tear down, we have made improvements to society.
The only way your dystopian future will come to light is in a "Hunger Games" type scenario, which I think the American people would be loathe to blindly accept.
