Hahaha.... someone that has never lived through an actual true food famine. (I have lived through two).

Price controls don't work, except for short term periods.... when you have a temporary disruption of few weeks (for an earthquake, weather, etc).

In long term famine, food that is price controlled disappears from shelves and almost never makes, and is resold in black markets at 3x the price (or whatever the market is).
