ECONOMIC CRISIS. Increases in the prices of meat and tortillas -- Mexico's primary staple -- fueled inflation and sparked consumers' anger Saturday in the sixth year of Mexico's worst economic crisis since the 1920s. The Commerce Ministry on Friday allowed tortilla makers to raise the price of the popular corn cake to 200 pesos per kilo (about 15 cents for a little more than 2 pounds), a jump of 54 percent. On Saturday the ministry authorized a 19 percent increase in meat prices. Inflation is running at more than 125 percent this year. It has averaged more than 50 percent per year since the crisis began in 1981. Few Mexicans earn more than the minimum wage of $3.10 a day.
