I think perhaps you meant to qualify your statement by time rather than space. I.e. "not much in the short term" rather than "not much in the big picture."
Certainly - if we have to wait until some company currently getting angel funding is big enough to hire up all the fired auto workers, we are really screwed:-) I think what you guys are doing is awesome, but think that it's basically impossible to predict much about long term effects: some YC company might create a system that saves the newspaper industry, or they might create the final nail in the coffin. Who knows... you (the generic you) just have to get out there and try and experiment and do your part.
