> The first employees will be "compensated" for their lower salary and extra hours, they won't get rich.
Um..? Not sure what your definition of "rich" is. My neighbor joined a U.S. tech company as employee 1000-ish when that company was at a few hundred $100M revenue, 8 years later they are at a few $1B revenue and his comp has brought him into 8-figures (USD). If he wanted to then he'd never again need to work in his life. I call that "rich".
Which percentage of all the people who worked in startups got rich?
If your neighbour got into 8-figures, it means that it's one of the very big tech companies, and the founders are super, super rich. But that's a very, very small minority of the cases.
The lotery makes a few people rich, but I don't think it would be fair to say that "the lotery makes people rich" in general. In general, the lotery makes people a little poorer.
