The other part of my comment I didn't write because I thought it would basically be evident without spelling it out: problems like poverty and income inequality aren't solved by tech innovators.
The actual problems that do exist in the U.S and the rest of the developing world are social problems. No amount of big disruptive thinking (by tech folk) is going to solve them.
If you look at SV's attempt to solve medical problems, you start to see where regulation and oversight are necessary for the difficult problems. Then you see why large governments, large companies, and exceptionally smart people with the backing of those organizations are the ones who need to solve the problem.
On top of all that, there's so often no actual intent to solve those problems. Poverty in the US is a big problem because the people who are capable of solving it just don't care enough to. In the case of government, voters are too self interested in the short term to push for it - how many times do you see complaints about hard earned tax dollars being used for poor people?
Even when the tech people do try to solve a social problem because the public has decided to care about it, attempts are misled and ineffective. If you look at the problem of diversity, companies are tryin to solve their problems at demand side. Big companies compete for female engineers to boost their numbers and smaller companies can't match their offers. This looks good on Apple's diversity report, but the problem is disguised, not fixed. Actual solutions, like encouraging women to become interested in STEM when they're young are few and far between.
So yes, I'd like tech innovators to focus on solving non-problems with life enriching innovations (slack, twitch, twitter, facebook, steam, VR, AR, bluetooth audio, etc) then waste time on misguided attempts that are way out of range for them.
