You obviously don't spend much time around schools these days. As a teacher for 12 years, I can tell you without hesitation, that the work ethic of our young people has gone to hell. As a witness to local farms who CANNOT, no matter what they pay, find Americans who will work (they show up for a day, sweat a little putting levy gates in, and quit), I can verify that America's work ethic (as a whole) has gone downhill, and not just in labor jobs.
And as long as we continue to import our laborers, it's only going to get worse. How many NO residents are still without work and/or displaced? Why the heck are they not in NO helping with the rebuilding (not saying that none are...)? My understanding is that NO had a very high unemployement rate prior to the hurricane - so where are all of them? Still getting free housing from FEMA?
As bad as you think it is, we still have a long way to go before we catch up to say, the French. I hire and subcontract lots of hard working legal labor in an area that doesn't have much of a Mexican work force. I know there are certain jobs I have to pay a premium on because of the lack of Mexican labor. For instance I pay about 33% more for masonry work than I would if I were a hour away in the big city where there is a Mexican labor force.
