This does not make sense in that you will get a lot of that back when you do your taxes.
You'll get a nice refund in what? April? For those other 11 months you're getting your paychecks lessened by thousands of dollars.
Also you are not taxed at a flat rate. Your rate will chance as the income goes up. For a single filer you are being taxed at 28% on 29K if we are using 120k as a baseline. So that person would still get something back after filing. The way they manage that money and the fact that this mythical person lives in a large city will determine their quality of life.
I'm not sure why you keep mentioning tax refunds. That's money that you will not be seeing until either Feb, March, or April. The rest of the year you will be taxed and your money will be disappearing even more when the deductions are factored in.
