Migrants took €17 billion more out of the Dutch welfare state than they contributed on average, every year, for a quarter of a century.
The idea that immigration “is good for the economy” is based on a false assumption and an incomplete equation. Moving every single person from China would “increase US GDP” too, but it most certainly would not be good for the economy. Or for the people who are already resident in the USA.
At around $20 billion per year for the Netherlands, that indicates an annual net loss of around $300 billion in the USA.
