I don't see how this is an insult, unless one has a natural bias against immigrants to begin with. I would like to see a neutral source confirm the statistic cited in this article, but I wouldn't find it surprising if foreign-born people are indeed more likely to work. Those documented immigrants have a lot of obstacles to overcome when coming to this country, and it takes someone with unwavering resolve and hard work just to get through that process. I don't deny that there are others that have a lacking work ethic, but I don't believe that that's the overwhelming majority in this population and would challenge anyone such as yourself to prove that that's not the case. I don't feel insulted because I work hard and know it for myself. And I find it more comforting that many of our foreign-born neighbors are working and contributing to our society. Still, it would be nice to have a neutral source confirm that the global benefits outweigh the costs.
