True. But decisions are made on tax brackets income falls in. The larger the ‘jumps’ in rates, the more impact.
For example, in deciding to withdraw from retirement accounts, a jump from 15% to 25% make it a bigger decision than a jump from 25% to 28%.
Yes, but in every scenario except the first $18k income (up 2%), you are at *worst* equally well off as today and in most cases (15%, 28%, 33%, 35% and 39.6%) better off than today.
