America is a nation built by (legal) immigrants, and on the premise that anyone can make it to the top. While that may be true, most new arrivals find themselves starting at the bottom of the pile. As HowMuch.net details, right across the country, households headed by persons born outside the U.S. earn less than households run by native-born Americans. But that wage gap varies widely per state, from close to $20,000 to less than $1,000. And in some places, the gap is even reversed, in favor of the immigrant households.
