A lot of People already can't afford food in the US. You think the Potato Famine was caused by not enough food and not governmental / economic ineptitude? That is like arguing bullets kill people not guns.
The potato famine (which had nothing to do with Louis XVI) wasn't even caused by ineptitude.
It was caused by outright cruelty.
Ireland had plenty of food at the time. It was just going to feed the English overlords. Potatoes were all that the Irish were allowed to keep, so when the blight hit, they starved.
