Sigh, no. Money is not flowing; company valuation might be, but that's temporary and only works if the company keeps delivering insane amounts of value.

So the founders sell plenty of stock while the price is high and then when their valuation crashes sure they "lost" half their net worth but the other half is still there.

I'm not saying that's what's happening, just making it clear that company valuation not being permanent is not a valid argument against money flowing to the top.
