So, here's the thing on reducing welfare payments to foreigners.
By creating a two tier welfare system you are effectively creating a situation where immigrants are far more desperate to find work, and, as a result, far more likely to accept appaling working conditions than "natives" - flat out rejecting welfare for newcomers would only exacerbate this.
Seems to me, this is a form of social dumping that is mainly going to benefit the patronat, at the expense of the rest of the country - and will push down salaries and working conditions even further.
So, expected for a right wing government.
You've summed up why I cannot stomach the RWPP. Its a self-fulfilling prophecy. You deny a minority public services, they form an identity based on the institutional discrimination, and then you wonder why they no longer identify with the "values" that you imposed on the national identity.
It makes the right-wing populists salivate though, because minority-interest parties are exactly the kind of diversion they need to convince the rest of the population to rally around them.
They are exacerbating this problem, because they need to stay relevant as a long-term political force.
