It makes perfect sense. Differentiating between a good and bad ones is the easiest thing ever.

1. Are they a net benefit to the country's finances? Do they pay more than enough taxes to cover the public services they use and then some. Or are they just a leech on the welfare system and a burden to society in general.

2. Do they integrate well into the society? Do they commit crimes?

3. To whom is their allegeince? The society they live in or the one back home? Do they promote the interests of their own ethnic group at the expense of the natives?

The first two are already available to state, tax, crime, welfare records. The third can be found out with a simple investigation.

1. As long as these are measured they are not a problem: Switzerland - and most of the EU countries - do simply not have a problem with poor people leeching the welfare systems, but rich people not paying their share: tax evasion by the rich is a problem going into the billions while social security fraud is around millions.

2. That's also measurable by crime stats and Switzerland is really tough in re-patriating people that broke the law.

3. That is something you cannot measure and where you cannot guarantee freedom or fairness in a society. What if I were to deem you too stupid to vote because you're advocating for a fascist mindset that might overthrow the democratic fundamentals? You wouldn't want that, I suppose.

So there's nothing to be done that's not already been done.
