From the most official of official sources.

I'm sure someone like Stefan Molyneux has 2 or 5 hour long videos on this subject that details every single horrible, heinous crime that was done to the German people during reunification. But I don't have time for that.

My view is that reunification was going to happen regardless of what governments or foreign powers said. But if East Germany had somehow remained a separate country. Itt would, by this point in history. Probably look an awful lot like Venezuela or the central Asian former soviet republics.
