I would like to see a book on Jean-Paul Sartre by Thomas Friedman... "Dieu se rit des hommes qui se plaignent des conséquences alors qu'ils en chérissent les causes" Jacques-Bénigne Bossuet
And, as we all tend to be self-interested, and getting beyond this (ie, altruism in the case of wealth) is usually an exception and not a rule, the organs which are written for and by them - Le Fig and Les Echos, FT, the WSJ, the Economist, et c., tend to be far more neo-liberal than the average. Wealthy folks tend to be far more neo-liberal in outlook than average as well, as neo-liberalism permits an even greater accumulation of wealth and power.
As for Friedman writing a book on Sartre, I'd pay top dollar for that too.
But I wouldn't read it. I can see it now: "Being-for-itself, this is sort of like me. I am for myself, and everything I write is a celebration of me". The quintessential Friedman. Fai de bèn a Bertrand, te lou rendra en cagant
