David Graeber's observations have never seemed more relevant here - in particular, how the ruling classes like to stoke resentment against those who do the jobs that are most essential to any society. Which are often done by immigrants. His 2013 bombshell essay,

But the logistical support man was paid six times more than the roofer and is also spared being branded a criminal drug-dealing rapist out to destroy our nation by angry men with bullhorns on street corners (either literal or figurative).
At the heart of a lot of nativist contempt for immigrants is the nagging inner feeling that it is they (the native born) who contribute very little.
