Today 60% of the government's revenue goes into paying interest on the public debt
You just can't admit you are wrong even if this post of yours contradicts your previous one.
which was created by criminal borrowing by the neocon government, 20 to 12 years ago (and only keeps growing).
Was the irresponsible handling of debt somehow due to the actions of the banks?
That borrowing came together with austerity measures (= taking more from the people, giving them less) and radical privatization (= giving people's property to banks for a pittance).
That happened after the debt got out of control.
