Well, regardless whether that's true or not, from an a priori standpoint and considering I'm paying roughly 75-80% of my income in income tax, various excise taxes, and VAT, I could fairly easily get by doing roughly 20-25% of the work I'm doing now.

And since I don't believe I'm all that special in the history of mankind, I guess it's conceivable that people in the past paying little to no taxes could've had heaps of free time 😄
