It's remarkable how much cash Big Tech has and how little they do with it. They could start
massive R&D centers that do fundamental research like Bell Labs. If they return cash to shareholders as stock buybacks, they'd self-indict they're no longer growing. Want innovation in USA? Big Corp needs to invest and employees need to pressure them because shareholders sure as hell wouldn't. Big Tech has little national interest, they're all global international corporations [1] – I really don't mean to start a national interst comment war, I am pointing out that they can invest if they so desire to. As of Nov, Apple has $190B, Alphabet $168B, Microsoft $137B and Amazon $86B in cash [2].
[1] This story got little coverage. $275 Billion. That's more than what Intel just announced yesterday to invest in Ohio. I consider 'The Information' best in class of SV reporting, yet not a peep from any major news source afaik: https://www.theinformation.com/articles/facing-hostile-chine...
