The richer you are, the more leverage you have and larger the material cost for these situations. A fellow rich friend gives you a little insider info that a stock you hold is about to crater. Do you sell some?
In other words, being honest is a tax, and the wealthier you are, the higher that tax rate. Given that, I think the only way to reach certain levels of wealth is by not paying that tax.
Therefore, I treat anyone at Musk's level of wealth as intrinsically untrustworthy. You don't get to be a billionaire by being a normal honest human. And if by miracle you should happen to, being a billionaire I think fundamentally changes your psychology such that you cease to be normal and honest. There may be exceptions, but I think they are exceedingly rare.
Billionaires are functionally a different species.
