Grows your produce? Raises your livestock? Ships your products to the store? Bags your groceries? Cleans your house? Watches your children? Makes your clothes?
Generally speaking, lower class people. Might be time to get off your high horse, don't ya think??
Edit to add, since I obviously failed to make my point even remotely clearly (oops!):
There has been talk on CM of what to do about the lower class, or welfare recipients. Many people have demonized the lower class to the point where they're seen as an abomination.
Some people think getting rid of the lower class is the answer. Let them starve, they say. Well, the fact of the matter is, the entire socioeconomic structure relies on the roles of ALL people, lower class included. The lower class would not exist without the upper, and the upper would not exist without the lower. THAT is the point. We all help each other, and failing to coexist over something so trivial as economic status is quite ignorant.
