Mexico just slapped a price cap on corn/corn flour. When will they learn?

Question

With the wealthiest country settled just North of its over-extended boarders, Mexico's green President Calderon decides to place a price cap on corn (32cents per bushel) and corn flour (42cents per bushel). The idea is to be able to limit corn tortilla (THE primary staple in Mexican diets) prices to no more than 78cents per kilo.
With the world's most successful economy directly to the North, One would think Calderon would take a hint...Caps only limit an economy. If he would introduces measures to encourage free trade throughout his country, this would easily remedy the competition the US Ethonal Industry is providing to rival the Tortilla market. Ouch!
Monopolies are hurting our neighbors to the point of economic starvation. What will it take for Mexico to take a hint, take control of their VAST wealth of resources, and climb away from these unhealthy monopolies???

Answer 1

Alas, people who should know better ignore the law of supply and demand. But government action plays well in the press.

Answer 2

Did you have a question in there somewhere? Oh, right, well we're lucky when we can get American politicians to not mess up good economic policies, how do you expected a incompetent crap country like Mexico to be smart about anything? Their corrupt politicians have the safety valve up north.
