Basically this in every capacity.

Immigrants are easy to hate and kick out. They are already probably vulnerable as a group, so kicking them while they are down while screaming, “YOU DON’T EVEN BELONG HERE!” makes emotionally immature people feel like they regaining control and protecting their country. This however has nothing to do with the other. Societies where racism begins to thrive will pick any vulnerable group. In Nazi Germany, it was the Jews. In China, it’s the Uyghurs. In many European countries, it’s the immigrants.

What exasserbates this further is that hating on immigrants (or any vulnerable group) worsens their conditions which makes it easier to point the finger and blame them for crime or lack of resources. Rinse and repeat. The spiral continues. The racists get more validation after pushing the immigrants down, and the immigrants become more frustrated with a country that doesn’t value their taxes and contributions.
