Earlier quoted context omitted.
Not only Germans but whole EU. The way EU works is by letting monopolies in a few west European countries expand their market to east and capture more value from everywhere. Yes, East European companies can also do that but usually, there is first mover advantage and other policies at local level which influence the ability to form monopoly through investment and expansion.
I'd love to know why downvoters disagree, if you start a competition between companies where some companies have better technology, state help or finance and put them against companies who don't have all that, yes big companies are more likely to become bigger if you combine the market where all these companies operate.
I mean, the EU - ignoring the name changes over the years - had existed for over 30 years before the fall of the Iron curtain and nearly 50 years before admitting new members from the the East. The idea that the whole thing was set-up and run based on the goal of economically exploiting recent entrants from the East decades in the future is simply silly.
