i like cheap meat

"I like cheap meat." Most Americans do: in 1970, we spent an average of 4.2 percent of our incomes to buy 194 pounds of meat. In 2005, we spent 2.1 percent to buy 221 pounds.

-- So one wonders, what exactly is the percentage spent on whatever the hell the bell of tacos and the arch de cow surrender put in the approximation of food they serve?
