If you apply the same unemployment metrics as Austria, Germany has pretty much exactly the same unemployment rate as Austria.
Give me a 1-million-person quota to import into Germany, and I guarantee you I will help the neediest in this horrible world. Starving, emaciated children, elderly and abused minorities around the world. I would certainly not import what Germany seems to have imported en-masse the last few years. I.e. import fit, working-age men from an incompatible culture, that don't know the language, and are able to cross an entire continent on foot.
If you have unemployment in your country then, by definition, you don't have enough jobs for the individuals already in your country. That is the whole point of the unemployment metric. To determine how well in-sync your economy is with the rate of population growth. If anything, unemployment should be a signal to kick people out, not let them in. However, neither up/down fixes it, because it's not a fixed pie. But your ratio is most certainly not going to be "net good" long-term or short-term by importing individuals that are unable to contribute.
> 1 Million uneducated people
If they offer education and are successful; someone like Elon Musk is 1/1 Million. Many will contribute; and some might return home in large enough numbers to bring some German culture back with them
I think there is a net good to some unskilled immigration - say 1% of the population each year. But I'm willing to be proven wrong. Is there some objective measure we can agree on which approximates 'net benefit'? For example, if total tax paid by these migrants over their lifetime is more than total welfare payments, would that indicate a net benefit?
