In every case it’s either going to be the same rate as now or lower than today. How does that make incremental work worse off than today?
Few go to their death bed wishing they spent more time at work.
A larger step in the marginal tax rate is a bigger disincentive to work more when one is at the cusp of the step increase in tax rate. Mpre, smaller steps in the rate are less of a disincentive at any point in total income.
This is basic economics, no matter your personal interest in more income at the expense of hanging out in your backyard with your dog drinking beer after the dog has taken your on your daily personal training course.
Economics apparently works differently for you. You may not be in the majority in how you view various incentives/disincentives.
