Many employees work very hard at startups juggling many different hats. I am sure it's possible to do a little bit of math to show that 1 year salary in a lifetime is not much risk at all, and in the end most employees take the same level of risk over a lifetime in terms of lost pay by joining startups or even companies that go bust, even if employees come later in the game; most startups fail. When they fail you have to find new employment which takes a few months. Add that over a lifetime, and employees that tend to work at startups easily lose a year or two of pay... had they instead worked for a large stable corporation with an actual career path.

My point is not that founders don't deserve a pay out. My point is that if you get a huge payout, employees that made that happen deserve a good part of it. It's good for everyone involved and the economy at large. And the startup ecosystem. It keeps wealth from concentrating in a few hands who can then affect the masses adversely and the economy as well. More people with money is better than fewer people with money. Competition is what makes Capitalism work. And part of that competition comes from the fact that many people have wealth. Not just a few.
