Ummm, you might have to cite your sources on this one. I've worked a few places in the US and while I have run into slackers, not sure what a defector is used in this context, I find that most people take pride in their jobs and work. Generally, I've found that most put in the time and effort they are paid for, so when they make a decent living and don't have to work multiple jobs to support themselves and their families they perform rather nicely.
But of course, that's just my opinion and I don't have a researched position to provide proof of that, I do know that the US has some of the best productivity per capita of the world, so I'd like some sources for your opinion so that I can research and provide counter examples or decide to agree with you.
