Germany is in a slow death spiral. What you are seeing right now is basically the scene from Animal Farm where Boxer, the working horse, has been injured [1]. The burden on the productively working citizens is growing, because money is required to finance the migration policy, oversized healthcare system, the huge pension payments for the ageing population (there is no pension fund) and government spending. Also, tax revenue is shrinking(!). The current government is asleep at the steering wheel, so industry may continue to leave the country, which will again reduce tax revenue, so the government will have to further increase the burden on the productive sector, which will again result in weakening the economy.
