YES! It would have to have some really fukked up conditions for me to want to say no (in a dangerous neighborhood, bathroom duty, etc) but I did that shyt before.
The #1 thing that made those jobs worse was knowing I was breaking my back and the check wasn't going far. 3 years 1 milli? That first check alone is paying for regular massages. I would quit my job today and do it. Suppose I bank 650k ish after tax, I can still start a nice ass nest egg and lock up the rest for interest bearing accounts. shyt if McDonalds offers 401k, literally take matching and throw in a bunch extra just to get closer to 1 million of realized income. If you are allowed to use tax advantaged benefits, you can minimize the tax hit from jump.
