Will Capitalism destroy us?

I feel that capitalism in it's current advanced form will spell the end for mankind. When the you look at the needs of todays society capitalism stands in the way of the solution. Global warming being my a great example. Why don't we have hydrogen cars for example? we know we're destroying the earth and we know a good many of the solutions yet we're held back by the constraints of our economic system. building stations across north america where people can purchase hydrogen is unimaginable today. but why? with all of our technologies today a lot of work can be performed with minimal manning. look at all the people out there who work pointless jobs, a generation of burger flippers? pumping grease into the veins of a continent. our people are not out performing the tasks we need, people are not out there tackling our problems on the horizon. it's time to think about an economic system which won't spell the end of us. we need to regulate more and ensure our planet survives us
