I am telling you what the man just said. He said Europe especially Germany opened their borders to get more workers. But as far as speaking the language is concerned. Try going to Silicon Valley and see how many speak English as a first language. English did not stop the Poles, Russians, Koreans, and Chinese from coming to America.
As far as Spanish and Greek unemployment is concerned, while a few are traveling to Germany. Its actually easier to get immigrants than it is to get folks who have a dole to fall back on. By the same token, America has 16% unemployment in the African American community yet they are not filling vacancies in Silicon Valley. However, a Chinese who knows no English does take the job.
Two of my wife’s relatives in Spain have gone to Germany to work (and send money back); the Spanish government is publicly encouraging any that can to do so. It appears that rather than depopulate EU states, they will just bring in additional populations - and I doubt it has anything to do with work (except at the lowest-skill level). Like the US, Europe is dealing with empty classrooms, homes, and maternity wards, and has to bring in people just to keep those industries moving (without creating a worse problem in Spain or Greece).
Most blacks don’t have the skill set required to work in the tech sector, and the education industry is determined to keep it that way; they are a captive clientele on the welfare reservations.
