"I live in California, which has the highest poverty rate in the United States, even though it's home to Silicon Valley. I see my rich industry doing nothing to improve the lives of everyday people and indigent people around us." This is trivially false. Over a hundred billionaires have now pledged to donate the majority of their wealth, and the list includes many tech people like Bill Gates, Larry Ellison, Mark Zuck…
The ACA could barely roll out a website without tragic failure, how have cell phones "dramatically improved" the lives of the poor? They're still subject to as much bureaucracy and denial of basic services as ever. 4G hasn't improved public transpo. I suppose the poor are no longer subject to long-distance fees during daytime.

Etc. And that's just easily measured benefits. There's good reasons why more people in Africa have access to cell phones than to clean water.
