Yeltsin was touring the US and stopped to see a supermarket in a small town. He was amazed at the quantity and diversity of goods. He asked the manager how many different items they carried, and the manager replied, “about 20,000”.
Seeing that kind of distribution system and the quantity of goods and foods available even in a small town, made him gnash his teeth at the Party apparatchniks who had been ruling Russia for so long, and keeping Russia from having similar abundance. He cursed “them”, and I think he lost his love for communism on that day.
We had an exchange student in 1998 from Kyrgistan. He said the same thing about the markets.
I went shopping in a Russian store in Munich once. They had tins of meat and fish for sale. Brand? The meat was labled "Meat" and the fish was labled "Fish". What kind and what type was not known.
Soviets also purloined the Marlboro packaging for smokes but can't remember what they called them.
Best thing about shopping in East Berlin? Stoly was about $.50 a liter!
As I recall, quite a few Soviet athletes & musicians who were privileged enough to travel to the US also lost their love of communism on their first trip to an American supermarket or shopping mall.
