Interesting point

A hypothetical rich man pays 10% of his wage as tax, 5% as living expenses. He is left with 85% for leisure.

A hypothetical poor man pays 10% of his wage as tax, 80% as living expenses. He is left with 10% for leisure.

Now if the rich man paid 85% as tax, he would have 10% left for leisure. The same percentage as the poor man.
