I'm disappointed that the USA didn't get credit for the vast world historical illegal/undocumented immigration levels the government has been inviting for decades. Millions work for less than survival wages with no legal rights and the government does nothing to discourage migration or employers.

Simple employer sanctions have proven effective in ending this kind of migration but US gov't imposes almost none.

Heck, even legal professional immigrants (H/L visas) don't have the right to change employers or resign.

If we had credit for all those millions, we'd be at the top of the league table here. Time for a recount. (We're number one.)
