No one born there (and where I'm from as well) is willing to do the hard jobs at the current market rate. Every conversation about a "labor shortage" seems to disingenuously pretend that wages are a fixed part of the equation.
Wages never rise because everyone falls for the propaganda that immigration is a "net positive" (and it is only a net positive for the capital-owning class who sell out their countrymen in favor of lower employment costs.) Do non-western immigrants in Germany contribute more in taxes than they receive in benefits (on average?)
