He does make an interesting argument, though: That when you get paid for labor, not all of your income constitutes a profit. Profit is that money received that is over and above the worth of your labor. Never thought of that. In any case, I'm perfectly happy on this side of the prison walls...
Nah. Thats why they don't call it a tax on profit, as in corporate or capital gains taxes that are taxed on the net, not on the gross.
It is a tax on any income, not profit, besides the exceptions that they allow you to claim.
And it, like any other fuel pump, sucks and blows.
