Nonsense. These feral vermin mostly have never worked a day in their lives. Immigrants who move for work add to the economy. So called asylum seekers are just moving their shithole ghettos to a place with better welfare benefits.
Europeans should look at how Americans were told the same BS; this is a bunch of crap. For every taxable “maker” we’ve trafficked here, there are several “takers”, and our “poverty industry” encourages it. Millions of Americans are employed “administering” these people in various ways (as teachers, cops, prison guards, interpreters, etc.) and the bill is paid by everyone else (granted, those gubmint workers kick back a small part of their high salaries in taxes, but it is a losing proposition for American taxpayers).
For sure, they’ll increase the velocity of welfare money and support payments.... however the costs of policing them and gross social costs will by far outweigh any benefit of muslim mooches and slugs.
