Most notably it resulted in a big reduction in the variety of food available because while some of the biggest companies could survive with the new lower prices (and work with the gov directly to set those prices) the bulk of small/medium sized ones couldn't, often as other expenses eventually increased while prices didn't.
I don't see how it will create more competition.
Not directly or quickly, no. Fully agreed that price caps and other invasive measures are usually counterproductive.
I was only pointing out that in a market economy led by profit-seeking CEOs, pushing pricing up is expected. Listening to those clips, they sounds downright sociopathic, but it's just another Tuesday in America.
The best way to deal with this is likely ensuring workers are paid a fair living wage. And take the appropriate measures to curb the worst of the inflation.
Price controls are a pretty big deal though. Especially in a low margin industry you run the real risk of putting firms out of business and damaging supply. They're very dangerous when done wrong.
And this is from a food cart, mind you - not a restaurant. And not a fancy food cart that people drive miles to try their unique food. Just a few years ago that sandwich would have been $8-9.
