Globalization, automation, and illegal immigration are the absolute biggest reasons why the lower and middle classes are suffering in the United States. Corporations are having no problems finding profits. We need to increase the demand for labor to give the uneducated a potential for a comfortable life in this country.
Maybe we are about to realize the true cost of food production, after decades of outsourcing labor to slave states (banana republics, etc). Prices, and pay, will both rise.
