We pray for peace, but most of the people coming here are coming from peaceful countries. I doubt ending the wars will make "living in a rich country at a high living standard for free forever" unnattractive.
Most people on the planet would probably like to move here, but if we just relocate millions of people here, the welfare state math doesn't check out.
German workers and laborers aren't productive enough to support multliple times their own number in welfare recipients. Printing harder and faster doesn't change that.
And Germans are already badly paid and most own no property. We have reached the phase where they lay down their tools and join the welfare line.
