In Canada, France, and South Korea there are laws against food monopolies, price gouging, and shrinkflation, especially during a time of National Crisis.
- Canada - The Competition Act now expressly includes as an anti-competitive act “directly or indirectly imposing excessive and unfair selling prices.”
- France - The French Criminal Code (Code pénal) banned coalitions from manipulating prices “above or below the level that would have been determined by free and natural competition”.
The United States is far behind other countries in controlling consumer food prices during a National Crisis and when there's a need to control inflation that drive many Americans into poverty.
In addition, Americans residing near the Canada/USA border in the northern states will often drive to Canada to do their shopping because the cost of goods is much cheaper than U.S. grocery stores. The same reason is true for the cost of medicine....much cheaper in Canada for the same medicine purchased in the U.S.
Yet, we want the world to believe we're the leader of a free world. A statement I now view as propaganda considering our standards are far below other countries with less resources. 
Also, a different spin on monopolies and collusion, for at least a decade after the government completed it's investigation...
banks colluded for at least a decade to manipulate exchange rates on the forex market for their own financial gain.
They controlled by colluding a
4 trillion dollar per day financial market that cost forex traders billions of dollars in losses.
The investigation revealed during court trials that
currency dealers said they had been
front-running client orders and rigging the foreign exchange benchmark WM/Reuters rates by colluding with counterparts and pushing through trades before and during the 60-second windows when the benchmark rates are set.
The behavior occurred daily in the
spot foreign-exchange market and went on for at least a decade according to currency traders.
