To what degree? I'm sure migration is statistically responsible for some percentage of worsening life conditions, but I doubt it's the biggest cause for anything specific getting worse. The far bigger cause is the ever-increasing inequality and subsequent extraction by the powerful.
If migration is responsible for 5% of an issue, and other causes are responsible for 95%, it's far too easy to make the population imagine the numbers are swapped.
