Isn't that by design? Ideally, business people will capture the market (usually though innovation and disruption) and then optimize the profits by removing costs as much as they can. In a "perfect world", Boeing wouldn't have any engineers, workers and facilities and they will just sell planes without delivering any.
They will be like licensers, middlemen or even better they build just one very powerful plane and whoever owns it has huge advantage over the rest so Boeing will sell "making sure your enemy doesn't have it" rights and extract the profits using a raspberry pi plugged on the wall at a Starbucks, running a code written by the lowest bidder on Fiverr and keeps selling planes and transferring the money into the shareholders bank accounts at the lowest transfer costs possible through the most tax-optimized scheme.
That's the ideal world Peter Thiel describes and he is right. Of course he shows concern for other stuff but that's because of ideological/personal/religious reasons.
