Is it worse now than during the Great Depression?

The United States economy was quietly making enormous strides during the 1930s with Americans getting a better education and industrious entrepreneurs inventing television, mass marketing refrigerators, and improving railroads. Today, no major industries are arising to pull the nation out of the current economic crisis. In addition, giant industries like finance, health care, and housing are spending huge sums of money on things that won't create jobs. Plus, the United States isn't following other rich countries and increasing its share of people with 4-year college degrees. Of course, this last point may have something to do with the fact that both political parties seem determined to flood the country with low IQ immigrants from Third World countries such as Mexico.
