Indeed, evidently some people think the plutocrats have their best interest at heart. Never mind needless economic disparity, geo-political crises or ecological catastrophes. Just go shopping or watch t.v. and believe everything they taught you in civics class.
These problems will not be solved by state enforced socialism or unenforced anarchy - the wishful thinking of several posters here notwithstanding.
History proved those to be either dictatorships or just unworkable (aka disintegrating immediately). And always poorer than capitalism.
Capitalism - with highly developed social democracy in several sectors, progressive taxation, etc - is the most successful system known to mankind when it comes to solving said problems.
