1. Capitalists control our society, and live completely different lives than the rest. A typical CEO is certainly quite privileged, and may even work their way up to true wealth eventually! But at the end of the day, they're still clocking in for at least 40 hours a week to do something they'd rather not do, and their life would be completely upended if they had to stop working for some reason. The difference between Pichai and Bezos dwarfs the difference between Pichai and me for these reasons, IMO.
2. Capitalists directly control ~50% of the capital in the US last time I checked. It makes sense to split any given pie in half IMO, at least to start!
