The problem in Western Europe is population collapse due to low birth rates of native populations. If they don't bring in immigrants their economies crater. Governments are facing tough choices.
No, their economy would adjust. Lower GDP and manufacturing output does NOT mean an economy craters, especially when you look at it on a per Capita basis.
As well, given the excessive amounts of social welfare and benefits programs the immigrants are a net loss. Very, very of them are more productive and contribute more than is taken.
Lastly, the native population may rebound if there was generally better culture and feeling about their country and future.
The UK is history didn't need millions of invading 3rd world immigrants to be the leading State on the planet, and they don't need it now. Neither does Germany or France.
