The coercion that a slave is subject to (whips, beatings, torture) is entirely different than the coercion that employer-employee financial exchanges supposedly entail (the need to work the sort of job you want in order to afford the standard of living you want). The difference is drastic enough to make the comparison ludicrous.
Today's workers obviously enjoy more comfort than slaves historically have, at least in the US. My point isn't to compare living conditions or the types of coercion that slaves and workers endure. Rather, that they both participate in coercive relationships and we should not tolerate either.
I want to sell my services doing X for a certain amount of money (or more!) Y. If I can get Y for X, then it is not a coercive deal as I WANT THIS TO HAPPEN, and, presumably the other party does as well.
FatherMcGruder, your arguments make no sense.
