I'm with saubeidl—while I, too, am deeply suspicious of anyone who comes from that level of privilege, and I've heard some shady stuff about Varoufakis in the past, you are refusing to present a) any meaningful criticism of his actual arguments, or b) any specific causal link between aspects of his background and reasons to doubt his work.
You just keep pounding on the fact that he is from privilege, but that alone is not enough to be suspicious.
At the very best, you are arguing guilt by association.
Guilt by association? Yes, he's associated with the WEF, a group of elite politicians and wealthy tycoons who meet away from the prying eyes of the public to discuss policies, and then tells us he's on our side.
They say you can know someone by the company they keep. The company he keeps are the Cambridge University students (who come disproportionately from private schools), mainstream media pundits and the billionaires of the WEF.
He doesn't just come from privilege... He never really left it.
But one can come from privilege, and choose to use that privilege to, effectively, infiltrate the ranks of the moneyed elite, seeking to make things better for the average person.
Some people have claimed that this is what he is doing. You have provided zero evidence that it is not. You merely keep repeating the same statements about his origins and his affiliation with the WEF.
I am not saying you are wrong. I am saying you have not supported your position in any meaningful way.
