That's not an entirely accurate representation, because after taxes you still use that money for housing and food and transportation etc. In business terms that 50k would still contain operating costs. So that $120 might still seem a lot.
That 50k a year should be extra money, the money left in your pocket after taxes, housing, groceries, other necessities and debts are paid off. That would give an accurate representation of how insignificant a $120 ticket would be.
They do exist and some of them swear Mac has better workflows (than windows because most of the time your options are Windows or Mac). I would call them loonies but I've seen some smart people use Macs.
