What plan? I do not know what reality people live in. I am an Indian myself, migrated 12 years ago. There are around currently 20000 students from India in Germany. I have talked to a dozen of them in my neighborhood, only 1 in 10 can even find a job post graduation in current market
Not sure of where you are coming from. But thousands come in and go every year. A few hundred are able to land a job after graduation / post-graduation (in Germany). Zero is not theoretically possible with so many universities looking for international students.
Canada, where immigrants came in under various immigration programs? As far as I know Canada and India don't have a trade agreement comparable to the one India has no with the EU. Hopefully one day. Apples to Oranges comparison though I think.
(I'm aware of companies abusing the LMIA system and I'm not saying that this or that level of immigration is sustainable)
