Because those are the projects which angels and VCs bankroll. Because those are the people who have disposable cash.
I was just reading an article on a conservative web site, actually one run by Ben Horowitz's father ( http://www.frontpagemag.com/2014/dgreenfield/cbs-colbert-and... ). It talks about how TV doesn't care about older viewers, rural viewers, and increasingly only cares about young professionals on both coasts, and how television programming is being focused on such people. Not sure how true it is but it makes sense.
Audre Lorde once said that the master's tools will never dismantle the master's house, and capitalism is not going to solve the fundamental contradictions of capitalism, other than by imploding, as so many economic systems before have done (feudalism, slavery, primitive communism).
Also, anyone who has done work organizing working class people knows the solution is not for a genius from MIT to swoop in with some corporation to try to fix problems wrought by corporations. You see what is possible and organize around that. The American white working class once had power, and it chose to send bombers north of the Yalu river, support a war in Vietnam, on and on up to modern day with Obama's support of the Honduran's military overthrow of Honduras's democracy etc. The AFL-CIO saw it's steepest decline under someone who never worked or ran a union, but was involved undermining foreign unions in cahoots with the CIA and American big business. And on and on. Now they go down to fundamentalist churches and watch Fox News as they age, and slowly become a minority in their own country. Empowering white, blue collar Americans gave us No Gun Ri and My Lai. Thanks, I'll pass. I'm glad to see the sun setting on the white American working class.
