It was the profit extractors that won the cold war.
The poverty divide between east and west Germany was so visibly apparent when you walked across that line. Today, both sides of Berlin are vibrant and thriving. The same can be said in every capital city that has joined the EU. Massive prosperity compared to the Soviet poverty.
However, the material conditions aren't necessarily better. It used to be that everyone was guaranteed a home, a job, healthcare, education, etc. Homelessness is now a problem in most capitals, many struggle to find a job at all, healthcare has generally been defunded and privatised, etc.
So many of us left because we clearly had no opportunities in our own countries after 89, especially after so much industry was sold off for scrap.
