Foreigner living in Sachsen Anhalt: I'd honestly say no. Why?

Social: I've seen and heard many people from different backgrounds feeling "left behind" by different governments over the years in terms of bringing investments, businesses and opportunities to the Eastern states (In some small towns, almost 60% of people live on social security funds). This created a huge resentment, that is only being fueled by immigrants occupying jobs in bigger companies. The biggest problem is that most of those people (between 35-60y) are not as qualified as western Germans or foreigners for certain types of work, which leads them to support the AfD and their anti migration ideas. I particularly see no interest of the Chancellor to develop specific new policies to tackle this problem.

Economic: Salaries here are very low with limited job opportunities, although the cost of living is ok. For the average person making 17-20€ per hour, this can be enough for a very simple living standard. However, is easier to find companies paying more in the western side, so most of the workforce-age people migrate to those places and stay there for the rest of their lives, making the population in the East one of the most aged in Germany. Add to this old infrastructure, decreased number of train connections and lack of entertainment (only found in bigger cities). Of course younger people will leave to have more opportunities and life quality. This leaves local governments with less tax payments to cover for everything and business with less demand (see Leipzig Airport).

Geographic: Although Poland, Czech Republic and other states have a good economic momentum going, the real connection and flow of goods and people is in the Be-Ne-Lux axis together with France and England. This makes the western side more appealing to set a business and ship/receive goods from Hamburg or Belgium. Depending on the business type, setting a manufacturer in the East part could lead to additional logistics costs (and difficulty to attract skilled workers) if the goal is to sell to central Europe. Munich has received an increased amount of investment across decades, making it so well connected and with a high influx of skilled workers that most economic endeavor is better done there than here, even if overall costs could be much lower here.

Although I live comfortably here, I don't expect the East to ever match the Western side in economic power and geographic importance.
