Well, I have worked for the city since February, and my 40% raise in income from my last job is mostly gobbled up by taxes, union dues and pension payments. So, technically speaking, while the actual amount of take home cash isn't 40% more than it was before, my long term prosperity has increased, because now there is some hope of retirement.
But seriously, it's the take home cash that has the feel-good factor, and a 40% increase in gross really only equals 18% net after deductions.
So, to be fair, yes, I am more prosperous, but I don't feel more prosperous.
But my house will be paid off before I am 40.
