Subject: Re: we don't need nurses, right?
Something clearly happened during the Biden administration. The data makes that clear. Otherwise, why would the number of people showing up at the border triple and quadruple, compared to the Obama administration?

I’d be more inclined to look at the period between Obama and Biden for the answer.

Did the number of people showing up at the border decrease significantly during that time? I seem to recall something about a wall during those years. And perhaps a bit of hostility toward immigration in general.

Perhaps when that intervening administration ended, a bunch of pent up demand for immigration into the US was unleashed.
