America has been so obsessed with thinking of itself as the "best country in the world!(TM)" for so long, it has meanwhile regressed into a failed state.
'failed state' is certainly hyperbole here -- there are large elements of society which continue to function, despite the problems at the national government level. It would truly be a failed state if, for example, the national government's performance level were propagated to the whole society.
So this amounts to saying that the U.S. is dysfunctional compared to the most developed part of the world, which is almost a tautology.
Not to say that the US hasn't made a lot of stupid laws and policies around immigration, but they're not alone.
