RikH 5pts The 2 issues you mention as the arguments of opporing sides are examples for issues that play in a much wider area.Getting staff. I doubt however if that could not be attracted on the world market. Likely even better ones. My experience with non-Northern staff is that their language skills often suck. In general they are more expensive than non-EU staff with proper language skills. You only need sufficient time to replace them. Basically the same issue all over the field. Welfare users. Good thing is that most immigrants are in working age (but so are those from outside the EU). However they are almost certainly for a big part at the lower income echelons. When these start to age (and they bring their families) the problems start. Low pay in for that group and high pay out (taks wise). Best thing would be short term employment at the bottom part (and getting them leave in time. A thing that looks better on that for EU immigrants (they return more often, although the bottom of the bottom part less than that again).Issue is that also on non-EU immigration European governments simply seem totally unable to do sherry picking. They get the average (often with no language skills) or even the crap more often than the cherries.
