The
obvious solution to the problem of abuse of the asylum system (which is in fact a real problem) is to hire more immigration judges so that claims are processed in a timely manner. Apart from getting rid of the asylum process entirely, that's the only long term solution. It's something Joe Biden made progress on (though he did overstate his progress), and Donald Trump reversed.
It doesn't show up in the short term numbers because it is a long-term solution. But Americans aren't interested in long-term solutions.
