If anything the average American should be demanding more, not accepting less.
There is no morality in sacrificing for your masters. If anything it is immoral to allow the market to swing so low by accepting a job with such a low wage. Let the masters herd sheep, the current herders would serve society better by not accepting such low paid work and choosing to die if better work could not be found.
If you don't mind me asking, have you found yourself ever having to make that sort of decision?
