Even if Trump's approach is worse than Biden's, which I'm not sure of, that still does not mean it is bad for the country.

Counting deportations alone does not count people who decide not to come at all.

Also, note that I did not say that we should necessarily be deporting more people. I am actually pretty neutral on illegal immigration. But I am trying to address the question of what is good for the country, which is a different thing from what my personal preferences are.
