If that is really Thiel's favourite graph, then I just lost an enormous amount of respect for him because of this obvious problem of the graph.
If all it takes is a graph to convince someone "hey, this rich person is right, I should do everything they say" they see that as a very small price to pay for brainwashing.
My respect for people naturally declines when they've gone out of their way to deceive me. This happens regardless of whether or not I agree with the goal of their deception.
The Bible doesn't say 'Thou shalt only lie if it helps you further your personal agenda', it says 'Thou shalt not lie.'
Derailing, but I bet you it doesn't. :P
