I think you misread the article. The article headline is paraphrasing Theil saying that Silicon Valley's majority support for Clinton is out of touch. Basically things are going well here, so they aren't aware of how ready the rest of the country is for change that will allow them similar economic prosperity. I personally disagree with Thiel, but I at least bothered to understand what the article was about.
Should a businessman run a country? I don't know.
Should a criminal terrorist enabler run a country? I do know: No.
