I agree with Thiel about Trump.
On the surface, individually, I think that Trump probably looks like a worse person than Hillary, but if you look at each candidate as the sum of their social connections - I think Hillary turns out to be much, much worse.
Hillary Clinton is heavily influenced by big finance. That's where the bulk of her friends and her connections come from. Even her son in law is an investment banker (not a very good one - He lost his clients 90% of their investment - But he still lives in a $10m apartment). At least Trump built houses and apartments for people. He didn't build his wealth by leveraging political power, insider information or asymmetrical reward structures.
I agree with Thiel that big finance is responsible for increasing costs of living. Big finance captures a lot of value from the economy but it doesn't create any real value on its own. Whenever I've spoken to someone who works/worked in finance, it's clear that a large portion of their profits come from 'grey area' insider trading.
I think that the main reason why most people aren't aware of this is because people like Hillary have been running the show and legitimizing the whole industry (and allowing them to get away with more and more stuff).
If Hillary gets elected, I'm going to quit software engineering and work in finance instead. If the world is getting worse, I'm going to have to adapt and become worse myself - I refuse to let myself become a loser. If you can't beat them, join them.
