I think anyone earning over $1 million Euros per year can afford to pay 75% tax ON EARNINGS OVER $1 million Euros without it affecting their lifestyle in any real way.
However, I do believe that no matter how many dollars you earn a majority of every earned dollar should go into your pocket. i.e. I think governments should discipline themselves such that their budget can be met with a top income tax rate substantially below 50%. If you have to tax anyone above 50% then you're doing something wrong.
