Alice pays 9% of her $117k income. Bob pays 18% of his $234k income. Those are lower tax rates than the present, so not sure why Alice would be unhappy with it. Carol pays nothing. Floor is the poverty rate, so no one makes infinity.

Unless I’m mistaken, if Alice pays 9% of $117,000 (i.e., $10,530), then Bob pays 11.7% of $234,000 (i.e., $27,400).

An 18% tax rate would apply to earners of $1,170,000 (i.e., $210,600 in tax).

The high end would be a 63% tax rate applicable to earners of $117 billion (i.e., $73.71 billion in tax).
