European countries are shooting themselves in the foot. It is about incentives indeed. If the mayority of the population is old, they are going to vote for people that promises THEM a free lunch.

Parasites invade vulnerable hosts, wealthy European countries are just that. These (and other) parasitic ideas pray on empathy which is in abundance until the host collapses.

It does not mean that Germany is going down for sure, but it will undergo a radical transformation in the not so distant future (see Italy for a reference).
