Interesting fact: there was a price cap on eggs 100 years ago, but it failed

Indeed, on February 7, 1923, Az Est wrote that the traders had to reduce the price of eggs to 22 crowns by Saturday. But in the countryside, the producers sold the eggs for 25-28 kroner, plus the transport cost and the sales tax, and the traders were not willing to swallow the loss, so they pulled down the shutters. The corner trade flourished immediately: sellers visited the houses, and village women sold eggs for up to 35 kroner in the market, saying that the fixing of the price only applies to the traders, not to the producers.
