@cubicgarden I am totally in favour of a cap, but would set it much higher than 10 million, given there are now countless billionaires. I think even a cap of 999 million would make a huge positive difference.
The likelihood of any of this happening is of course vanishingly small, but the idea of a 10 million cap seems way too low to me given the amount of wealth around, and even less likely to ever become a realistic proposition.
