How is the debt accumulated and abused by many governments Varoufakis' fault?

Didn't say that. I said the previous government made a half assed almost decent job to short things out and they nearly made it, but Varoufakis party at that time Syriza forced elections in 2015 and came to power.

The problems were there long before Varoufakis had any influence.

The problems were long before him and still exist.

He just happened to be there when the house of cards collapsed.

He just happened to cause more problems in a very small time frame and he was the one the made the house of cards collapse.

He was 100% responsible for the closing of the banks for a good couple of months in 2015 and for capital controls that exist until today.

But at least he sold a lot of books...
