If one of these things isn’t true, you’re either a fool or those productivity increases aren’t real.
A simple example: if someone patents a machine that makes canned tuna 10 times faster than how they're currently being made, would tuna factories make 10 times more money? The answer is obviously no. Actually, they'd make the same money as before, or even less than that. Only the one who makes such a machine (and the consumers of tuna cans) would be benefited.
10x to 20x is in relation to time, so something that would have taken 2 weeks (80 hours) would be done in 8 hours to be 10x.

In other words, how are you taking advantage of all that extra time you claim to have?
