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.
Our government had taken IMF loans with the goal of expanding industry to sell products to the West. We did, then we were prevented from selling finished products to many countries. Some of the production was redirected internally and towards trade with other socialist countries, but the loan denominated in dollars remained.
Then the IMF demanded we pay back the loan early, while mostly only allowing us to export food. Today this would be called sanctions. This was a tactic to intentionally create scarcity of food in the country, which coupled with constant propaganda (especially from Radio Free Europe) and arming and funding local fascists (including the famous snipers shooting into crowds), culminated in a bloody coup in '89. Similar tactics have been used by NATO powers against other countries.
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.
In the GDR "job security" meant they told you what to work, choice was limited, if you always played by the rules, and if you didn't like that, you'd go to jail.
In the GDR no-one was guaranteed education. Today in Germany everyone can study whatever they want, in the GDR <5% of pupils were allowed to study, based on the status of their parents. Participation in events and workshops in school was based on the status of your parents or your participation in party organisations (FDJ, Young pioneers).
The GDR was on the verge of bancrupcy as were many other Eastern block countries at the end of the 80s, with low productivity but unsustainable high subsidies for food and flats. Poland went into bancrupcy and all other Eastern block countries were near that point (often because they took Western credits in the 70s and early 80s to increase consumer good production but couldn't pay back later)
(Anyone interested in Germany I recommend "Das Ende der SED: Die letzten Tage des Zentralkomitees" with protocols from the meetings of the central comitee).
Romanian leadership took a lot of loans from the West and spend the money on large industrial projects with Western technology which was either obsolete or becoming obsolete (Dacia-Renault, Olcit-Cytroen, CANDU for the nuclear energy, Rombac-British Aircracft, etc...)
This was a huge bet that did not work - but it was all done by Romanian Leadership. The West did not ask Romania to borrow, Romania asked to borrow. When the bills came due at the end of 1970s Romania asked to roll over their debt. Unfortunately for Romania at the same time US FED (Volcker) was raising the interest rates sharply to combat inflation. So rolling over the debt was very expensive. This was not economic sanctions aimed at Romania - this happened to every borrower that had USD debts (including regular people in the US).
Romania choose to pay the debts and the only way to get USD was to sell resources - because the industrial products were obsolete and nobody in the West wanted to buy. So Romania sold food and whatever oil they still had and whatever steel they still had. For the Romanian people that meant food shortages, heat shortages, electricity shortages...
This was done by Romanian leadership. It was not economic sanctions from the West.
