Germany Immigration by Country

I believe he means, that the pledge is threatend to be dismantled by right wing extremist in the German parliament. Although, there isn't realy any pledge in the first place, just mildly philanthropic pragmatism.

I threatened to give a homeless man a dollar once.

How did he take it?

Why would you use wikipedia? The German statistical office has much more accurate data (while not all countries are counted all the more significant ones are) https://www.destatis.de/EN/Themes/Society-Environment/Population/Migration-Integration/Tables/foreigner-age-groups.html

It's still BRD. The political and legal system, constitution, etc. remained the same. The East accpepted all of that and joined the BRD. Still, it wouldn't be correct to say that East Germans immigrated. They stayed where they are, the country around them changed.

You got Kosovo but not Serbia?

The "fact that they can't be denied any German social welfare benefits if they move there due to their EU citizenship" is absolutely not a fact.

Contrary to what right wing nutters and British tabloids (as if there's a difference) claim, freedom of movement in no way guarantees access to any kind of social welfare.

There are restrictions to some benefits but for instance things such as Kindergeld (monthly child benefits) are entitled to anyone residing with a child in Germany.

See translation of https://www.kindergeld.org/kindergeld-fuer-auslaender/

"Foreigners living in Germany are also entitled to German child benefit if they have the corresponding settlement permit or other residence permits that entitle them to receive child benefit. Nationals of EU states and the European Economic Area (and equivalent states) are entitled to child benefit even without a settlement permit or other residence permit, as these are on an equal footing with German citizens due to the free movement of EU citizens."

If someone would move from Saxony to Hesse, he could be expecting to receive the same benefits under the same rules there, as any native Hessian, irregardles of their reason for moving or family history. Why should it be differently for our neighbours from Romania and Bulgaria? In fact, Germany should support those country to build an equally strong safity net, so that Germans can expect an equally safe and productive way of living, if they chose to move down there.

Not saying it shouldn't be the same. But there is still a difference in language and quality of life.

Building a social safety net in Bulgaria and Romania is near impossible because of the corruption there. Germany ranks 9 on the Global Transparency Index while Bulgaria and Romania both rank 69 (not nice). They're some of the most corrupt countries in Europe, creating a functioning social safety net there is near impossible. So I totally get why people there would leave to Germany or similar western EU countries. https://www.transparency.org/en/cpi/2020/index/nzl
