@stux I have an idea. Tie the max amount of wealth a person can acquire before it's taxed at 100% to 3 million times the maximum (since there are various qualifiers) untipped minimum wage per hour, so $7.25/hour (federal minimum) becomes a cap of $21.75 million.
If there's a difference in minimum wage depending on where their primary residence in the US is, then it goes in descending order forfeiting the difference to the various jurisdictions
@stux Example: they live in Renton, Washington which has a minimum wage of $20.29/hr, so that's a cap of $60,870,000 overall. Everything above that is forfeited to Renton.
Washington has a minimum wage of $16.28/hr, so anything between $48,840,000 and $60,870,000 is forfeited to Washington state.
The US untipped minimum wage is $7.25, so anything between $21,750,000 and $48,840,000 is forfeited to the federal government
