> Or worse still, the super-rich will realise that they can spend many times the wealth cap per year consumable/disposable items (so long as they stay under the cap, or get back there by year-end), and become more wasteful. "Might as well spend a few million on a private jet, if I don't, I'll hit the wealth cap!".
This is a very interesting point! I'd worry less about rich folks spending to be below the cap (that money re-enters the economy), but rather evasion by sending money back and forth between a small set. Clearly evasion would need to be monitored.
