Oh yes, now you've started!
1) I'm not from eastern Germany, I'm from Manchester. I just happen to have chosen the eastern part of your beautiful country to live in for work reasons.
2) 'Your' taxes have rebuilt 'my' half of the country. Do you pay a 'Solizuschlag' in your taxes? Because I do. Meaning that I pay extra tax to help fund the rebuilding of all of Germany (that includes the areas of the Ruhrpott which are dying). Is it not true that wages in the eastern part of Germany are kept deliberately lower than the west, for doing the exact same hours in the exact same job? And yet, prices in the shops are the same?
3) Whose taxes paid to rebuild the western part of Germany after WW2? It certainly wasn't 'your' taxes. West Germany's reconstruction was funded by taxes paid the British, French and American public, as a way of ensuring the the BRD would become a financially strong and successful buffer against the spread of communism from the east. This especially includes Bavaria, possibly the area most under threat. In a similar fashion, taxes paid by the people of the EU funded the rebuilding of the former GDR (and later, Hungary, Poland, Czech Republic, etc.) to ensure that the threat of communism would not get a foothold in Europe again.
4) I'm going to presume you're from Bavaria. If you know your history, you'll know that Bavaria was an primarily agricultural state before WW2, and not very rich. In fact, one of the richest states in Germany was Saxony. When the Allies carved the country up between them, they moved all the financially viable companies from the east and set them up in the west. Including Audi amongst others. The German High Court was moved from Leipzig, and all the publishing houses, to areas of the west which were under US control - Bavaria, BW, Hessen, etc. How many moved back after the wall came down?
5) The football clubs in the GDR were not works teams. They were sponsored by state-run companies. When that system ended, the rich clubs from the west took all the best players, able to offer them more money, and made absolutely no effort to fund or aid the rebuilding of the stadia or footballing infrastructure in the former east. Funnily enough, when the Bundesliga started in the early 60s, this solidarity was one of the goals of the new league system under the DFB. Conveniently forgotten when the clubs from the 'new' states really needed help.
I would like to hear your response to these points, bayernblade.
