Since they're the ones doing the taxing, gun confiscating, passing out of welfare, making sure kids don't wear crosses to school, making laws against any car that ain't a Yugo, taking property away from people and giving it to snails, and confiscating hard-earned dividends and interest,* what do they have to bitch about? ;)

Conservative talk radio is appealing to many Americans because it is a validation of things that they already believe--beliefs that much of mainstream culture holds in contempt. My mythical Kansas family probably listens to Rush...but not that much since they're probably working much of that time.

*and yes, they are earned. They are paid in return for value received.
