I made an account, just to tell you, to not move to Germany. Unless u plan to stay unemployed and live from social assistance, Germany is a very bad place to earn money, because u pay the most taxes then everywhere else in the World.
Also Healthcare is not free, you pay a certain amount every month from your income and then in the end of the Day, the Healthcare system is just very bad (staff shortage).
I could list a lot more reasons, but me as a german are actually thinking of leaving the country.
And yes Düsseldorf is dogshit (i am from Cologne).
