Those of you who've never even considered the problems of minimum wage laws may find this section of the Wikipedia entry on the subject of interest. It provides (IMO) a decent, evenhanded discussion of the cons and the pros of placing a floor on earned wages.

...Except the studies cited only cover factors that are not being actively concealed, such as employers who are hiring illegal immigrants at below minimum wage.
If anyone ever pushes through a forced amnesty program, there will be war, with the illegals fighting alongside their "exploitative" employers against the well-meaning socialists who will be unable to comprehend the war they find themselves embroiled in, in any terms that do not include magical mind-control techniques.
