I assume you are either already rich or want to become rich because of your startups. Why wouldn't you expect people to want to also be rich?
I will say every time I hear someone claim that their employees should want to join them for non-monetary reasons, I assume its to try to keep more of the rewards for themselves.

You assume incorrectly. I am not rich by the standards of rich people (although I am rich by the standards of many others, but I think it's safe to say that most of the people reading my comment right now are wealthier than me), and I don't form startups because of a desire to gain wealth. I have no actual interest in amassing wealth as such.
I form startups because they give me the opportunity and freedom to engage in projects that deeply interest me.
"Not rich by the standards of rich people" is a moving target as your social class improves and you rub elbows with the more wealth as you make more money. There are people making $500k a year in the Bay Area or NYC who don't think they are rich. But the simplest dividing line I can think of is "has fuck you money". That is, could you (financially, not socially or being bored) retire tomorrow if you felt like it.
