yes, they do have to send the filth back where it came from --- but, also - keep the good ones.
People talk atm about Germany and it's 'problems' with refugees --
and, yes, that is true -- but, what is also true is that Germany has got a large amount of labour from this as well -
that is not to be forgotten. Why?
Because one needs to look at exactly why Germany became the industrial/economic powerhouse of Europe - and, it mainly comes down to one thing -- labour - cheap labour -- immigration.
We should never forget that West Germany absorbed the entire East Germany - and, yes, although many of those were very educated - Germany did very very very well out of it once they got through the integration.
With the 'new' immigrants - they sure will have some problems - but, they 'will' get there and not only that, but, in the end, economically - they will charge ahead again.
Yep - they sure do have to dump the crap - I have no argument there.
Now - if you contrast that with the US - who have been now for many years - raiding and getting rid of large numbers of illegal immigrants - through the Obama years and now with Trump - well, what you find is that America has had continuing labour problems --
a really good example is the town of Cactus - which exists on processing meat - ie. killing and cutting etc.
From memory - it was worked mainly by Hispanics - then, before Trump came to power - mass arrests happened - and, Cactus struggled -- no Americans will do the work.
So, they have now gone to different ethnic groups -- refugees for Asia and god knows where - I forget.
The point is - that powerhouses are built on cheap labour -- no matter where they are -.
Now - once Germany and the like settle down with employed immigrants - they won't be an issue - it's when you can't employ them or they won't be employed that gives you problems.
Basically, if America stops it's cheap labour --- it's stuffed. There is an interim here between using cheap labour and full automation (robots) --- atm, industry needs both.
