In today's society having tons of money is the best possible approximation of not needing money at all, which makes having values beyond it (and following them) a lot easier.

Not that I'm criticizing Musk as I respect him as much as I have low consideration for Zuckerberg, but if Tesla was a startup struggling to stay afloat it probably would have changed something.

"Also having values that extend beyond money is, ironically, a lot easier when you have plenty of money."

In general, yes. But I believe that neither Musk, nor Zuck have "plenty of money". Not when one of them ones to go to mars and the other one control the worlds communication. As you need really much money for both.
