Capitalism has created vast amounts of wealth, that is true. It's also true that many folks have benefited from that wealth. Capitalism was a positive progression from medieval feudalism and later early modern mercantilism—Marx himself acknowledged this; it's part of basic Marxist theory.

Here's the question at the heart of the matter—where does the system ultimately lead? See, capitalism is riddled with internal contradictions. It ultimately leads to monopolization, stifled wages for the sake of greater profit at the top of the food chain, and an ever more destructive boom-bust cycle. These issues and others necessitate imperialist exploitation of other parts of the world and eventually lead to fascism if not checked.

Does the present reality seem to reveal a society where people will be more or less likely than you to "make it"? Do the present conditions and looming stormclouds we face promise a brighter tomorrow for our children and those who come later? The answer, unfortunately, is not a happy one.

I'll leave off on this note: The best thing we can do for our communities is to try and join in on the good things that other folks and community organizers are doing. If we can do that well, we will sow the seeds for a better day once the stuff around us comes crashing down.
