Exactly. Dude has some sort of axe to grind. The situation could get bad ... yes ... but not for the reasons he explains. These Angels aren't going to bring down the economy when they lose their bets. When the market crashed after the dotcom boom regular people lost significant parts of their savings, and that contracted demand across the economy. The only part of the economy that contracts in the Cuban scenario is the market for Yachts and Teslas (exaggerating, but you get the point). The only way it spreads is if there are other macro factors that we haven't been told about by Cuban (because he doesn't know or understand them).
