I do know people who figured out their marginal hourly rate after taxes, and decided to cut back their hours worked to stay under that.
When figuring the hourly rate, one must take into account not only taxes, but loss of unemployment compensation, earned income credit, etc. There are definitely folks who do this and choose to work less because their net hourly rate is not compelling.
Well, like I said, "I suspect this is a rare taste, like people who like yak butter. After all, you have to be willing to spend an inordinate amount of time studying the tax code before you can figure out how changes in work habits will effect your total tax bill over the long term, and few people are willing to make that effort."
