Where did I say I lose money?
I was simply describing how the increase in hours has diminishing returns to take home pay. Factors such as increase taxes and increase contributions to my Roth are the reasoning. It all comes out in the end when you file your taxes if you've overpaid or underpaid, there's no "secret" income threshold, it's directly related to your deductions and tax credits. In other words, it's a simple math equation as to what you bring home every week. The government has yet to tax people 100%.
Under your current logic anyone who earns more than their deductions and tax credits is losing money. This is also know as not paying any taxes. In order to achieve this you must earn on the lower end of the income scale generally speaking.
It's interesting you claim unions promote mediocrity, yet you are doing the same thing by telling people they work too much based on their tax bracket.
I'd rather work for a dollar and pay a quarter than not work for the dollar to avoid paying the quarter.
