you need the revolutionary to give life a pulse and a direction. i'm fairly positive that the time will come in which the abusive practices of today's banks (along with many other institutions of today's capitalism scheme) will be regarded as immoral and today's so called anarchists who fight against that system will be regarded as heroes.
So make me a list of all the non-capitalist countries that have provided their citizens with a better quality of life than capitalist ones.
No need to say that money isn't everything, I am talking quality of life here.
If you want to do away with capitalism you need a replacement that hasn't already been shown to fail.
