I think that it would be wiser if the government actually make it more difficult to hire people from abroad if they are unskilled workers, this has started in other EU countries. But on the other hand make it at least reasonable to bring skilled workers, meaning highly trained people who are actually going to enrich the country's economic system.
I had to wait for my visa for a EU country for 6 months because they wanted to make sure I would not live off their welfare system, and I was actually going there because I had won a scholarship with everything paid so it really made no sense to make me wait so much (and by the way miss so many classes!!!).
I do not know if this restriction of working permits makes any difference between unskilled and skilled migrants
