Today the Apple Dumpling Gang provides hard evidence of that:
(How do you define middle class? It depends..., The Apple Dumpling Gang, Chron.com)
By the strictest of definitions, American families that fall into the middle fifth by income are middle class. By that standard, families making between $38,048 and $61,735 (in 2010 dollars) would be middle class.Remember that, when you hear progressive bloggers, progressive politicians and progressive members of the media talking about "making the wealthy pay". If you have a household income of $75K, you're the "wealthy" and they want to make you pay "your fair share".
It's an important data point in the upcoming debate over which direction we want our economy to go.
Added: All of this makes you wonder what type of middle-class jobs the President and The Apple Dumpling Gang are speaking of? Certainly not professional positions that require a degree, or an advanced degree for that matter, because most of those, outside of entry-level positions, have pay scales in excess of the middle class.
