Economic immigrants will save the European Social Model

The way to address the aging population of EU effect on state finances in UK, Greece, France, etc, is not by dismantling their Social Models (eg see changes in the NHS) but by adopting a more open (realistic & humanist at the same time) policy (by EU & member states) on economic migration to the EU. Thus enrich the revenue base of the healthcare and other welfare systems instead of dismantling them.
