In some old video games, there’s a coding… gap where if you get too many lives or points or whatnot, the number just sort of maxes out.
Money should work like that.
No more billionaires. Money beyond a certain point should just bounce off them.
Instead of, “Oh, I’m sorry, you don’t seem to have enough money in your account to pay for that,” it should be, “Oh, I’m sorry, you have too much money in your account and can’t accept payments anymore.”
