During the Middle Ages and Renaissance, Christians were not supposed to charge interest. Therefore, the most common moneylenders-to-kings were Jews. They could loan money at a profit, and were thus more likely to lend it.
But whenever the King’s debts got too large to repay, he began to demonise the Jews. And eventually came a pogrom. And hey-ho, the debt went away along with the Jews.
I’m seeing the demonisation of banks. I wonder how long before government throws a pogrom?
Well, they’ve already bused mobs to bankers’ houses, though that was kind of a bust overall.
