There is a very big food problem... in the US.
Also, there is a very annoying problem with people of other colors in the West. I do not want to have to tell my kids to be afraid of "some people" when I take the subway, but I also do not want them to be unsafe. This is another reason to avoid the West for raising kids. (Just one last: in Japan, parents are NOT allowed to take their kids to school, kids have to go by themselves. In the West this would be considered irresponsible. I want my kids to be happy, free and safe.)
