I’msure they will just ensure they will never reach 100m and stash their cash somewhere hidden. So won’t work that well. But might work for a one off cut. Which is good.

Why didn't Bezos just stash his assets somewhere hidden so that he wouldn't have to give $38 billion of it to his ex?

Because it doesn't work that way at that level of wealth, especially for tech CEOs. You can't just hide billions worth of shares in a company.
