That's a very bold sentiment and one that is probably well far away from reality as you can get. As you have just stated capitalism in it's myriad forms is GROWING not shrinking and it'll be another 10 years before the current cycle starts to even out.
There are simply too many factors and variables to say such a thing. It will take a massive occurance for captialism to cease. And I promise you such a thing like a revolution to forsake the tenents most Americans and even Canadians have been raised upon will not get enough popular sentiment that a true revolution will occur that will come to any type of fruition. Western society if anything is decadent and we like our stuff. Taking away our shiny bobles and the capacity to get such things will not go well for those attempting to do so. Western societies,espcially many Americans have a decided distrust of authority and the government in at least some manner. Most will not stand for a government who will feast off of their contributions and give them little choice in the matter. In a capitalist society you are a slave to the system but many people have a choice of WHO they are going to be a slave to. You do not have that choice in a communist society. The government owns you. They own any idea you may create. They own any advancement you come up with. That isn't true in a capitalist society as can be readily seen when a lot of Western tech is sold overseas.

And I hate to break it to you humans are not basically good. We are basically flawed,selfish and greedy. Most people do not agree we are all in essence equals especially if we all have different skill levels, interests, and abilities. We agree that we should get fair shots but beyond that...no.

In short there will be no revolution at least not in the way you are thinking. I just turned 27 and if truly by the time I'm 52 and there are 0 capitalist societies on this planet I have a feeling it will be because something else other than a wave of communist doctrine swept the world. And if that DOES come true. I'm telling my kids do not work just get a book learn as much as you can leech as much as you can from the puppets that are stupid enough to provide you with all the food you can eat and clothing that you can wear. So that when the current system crashes and burns that hopefully you will be in place to make the best of a reborn capitalist society that will rise out of it's ashes.

Considering what I see of their living conditions and all just because they are living on less than two bucks a day doesn't make me jump at the chance of living their lifestyle.
Take that family that is getting by on 2 bucks a day let them come over here and likely work less get paid more and likely live many times better on the 80-100 dollar a day landscaping job that they can get by simply standing around at day work sites.
I mean you need to look no further than the waves of Mexican immigrants into this country. Many are working just as hard or less than they did back in Mexico but they are making so much more money here that people willing risk their lives to get the shit jobs most Americans do not want to do. They do this because THIS is a better life than what they can manage in their little pueblos and ranchos back home.
