...to keep the present level of pensions and health benefits the EU will need to import so many workers from North Africa and the Middle East...

I'm not sure about that. When Europe has and overall unemployment rate that's about double what it is here, that says it has an undersupply of jobs available.

So why would it need to import more workers to fill jobs that don't exist?

You have a very good point. However, they need younger workers to pay for the benefits to the baby-boomers (like our SS) -- it's just bad luck (LOL) that there are no jobs for them, as you point out.
