That may be true, but they can't control everything.
It happened in the Weimar Republic and Zimbabwe, and I doubt they planned on it happening.
Actually, they did.
Weimer Germany printed currency to pay off its war debts.
Zimbabwe printed enormous amounts of money because Mugabe wrecked their economy and is the stupidest leader on earth. I'm dead serious. They did it because he destroyed their economy and couldn't generate hard currency, so they ramped up the printing presses to meet the country's obligations.
