nursing is a major industry in the filipines to the point in America they pretty much only need to pass a qualifying exam. I always assumed so many nurse are fillipinos is because they`re simply tougher and can handle the work better.I`ve recently been to many healthcare places and I admit I can`t do it.
I don't know if nursing is tougher or if the filipino culture builds tha toughness, i do know that it is pretty likely that many filipinos have relatives that have gone that professional route and they know it is a good way to help in their quest to immigrate to the US.
Maybe the same thing could be said about the Vietnamese and their dominance of the US Nail Salon market. Or the Patels and the motel industry.
