PG seems be becoming more and more disingenuous. People using the word "earn" almost always mean "you can't get this from wages." This doesn't mean that the effect of growth isn't real - almost any business that scales even moderately, but none the less scales, and is profitable, can make its owners millionaires or better. But this does not mean that those riches were "earned." Or that the person who started the business had more glorious suffering than some rando who works 80 hours a week of part time jobs to keep a roof over their kids' heads. Rather, it is inherent to finding a scalable business and not screwing it up.
