[Mr. Mojo]

the fact that most Americans were third worlders when they came

Europe is the first world, not the third. ....And most Americans are of European ancestry.

Of course the early immigrants were mainly from Europe but they fit one of the definitions of third world: - economically disadvantaged, politically and culturally exploited, dominated peoples - in these respects they are not dissimilar to the Hispanic immigrants moving North. BTW - Most Hispanics share European ancestry as well.
