82% tax wedge is not the same as taxes, or even the contribution of an individual.

Also nobody is talking about taxing income even more.

I do agree however with the sanity part, although I think of a whole different subset of people than you.

Effective tax rate is what you should be looking at. The most efficient tax rate is one that describes a exponential saturation, where it starts growing faster once it reaches the point where you have too much wealth.
