What a nonsense.

occupied by communists after the second world war

Polish communists occupied their own country?

There was very little food, if any at all in stores.

You might have heard about, you know, the war and the real occupation, nazi one. Requisition, destruction, mass murders, death camps. I wonder why that stopped. Who ended it.

I remember specifically

Unless you are 95 years old i doubt it was "you specifically". And also:

I remember specifically that the only thing being in stock in stores was vinegar because the shelves were empty

At least get your propaganda sorted out, dumbass, those were two different separate pieces, the vinegar one was about the 80's (and equally false as the other one).

Everything of value Poland produced, like food, went to the USSR. The only import Poland got were things like matchsticks.

As evidenced by the rapidly rebuilding and repopulating country being made entirely of matchsticks. Yawn. Seriously at least get something less boring, go read some IPN book or something for more plausibly spun propaganda instead of taking your historical knowledge from Jebzdzidy.

What were conditions like everywhere else in the world after the biggest war the world had ever seen?

Everything of value Poland produced, like food, went to the USSR.

Let's see some sources to support this bold claim. I'll wait.

"I remember specifically"... Damn, I'm sorry you had to survive on only vinegar and matches, grandpa 🤣

Then why didn't 3 million people died out straight way like what British did to bengali people (I am from bengal btw).

Sounds like the stories I've heard from people of that generation in west Germany. Things didn't get better until the Währungsreform of 1948, and didn't get markedly better until the US dumped in money (with strings attached mind) via the Marshall Plan. Europe was decimated by the war, regardless of which class was in charge.

Ahh yes, so we should have just let the naxais have the place. That would obviously have been preferred

Słuchaj, pierdolisz. PolandIsAStateOfMind napisał wszystko co trzeba, jedynie piszę abyś był świadom że paru polskich komuchów tu jest którzy są chętni do zwalczania typowych głupot jakie ludzie jak ty lubią rozprzestrzeniać.

A Poland immigrant in Canada had testified about Communist rule in Poland, so I can expand on your story. There was free food under Communism, but people need to wait in a long line because the Soviet Union used the financial institutions from the Western European countries for the recovery after World War 2. Since the Western Europeans want to sabotage Communism, their institutions attempted to overchange the Eastern European countries with huge debt for the financial assistance and this debt-trapping is the current practice of the Bretton Woods institutions like World Bank and International Monetary Fund to create third world problems in former European colonies. Also when there are evidence that a person is subverting Communist rule, the Communist government will conduct search within a more reasonable ethical boundary than the police search in the US.
