Ein Mann geht in ein Kaufhaus in der DDR. Er fragt den Verkäufer: "Gibt's hier keine Socken?" – "Nein, hier gibt's keine Hosen. Keine Socken gibt's in der zweiten Etage."
Translated (roughly): A man visits a department store in East Germany. He asks the shop assistant: "Do you have no socks here?" – "No, we have no trousers. No socks are on the second floor."
(The joke relies on the word order of German syntax; properly translated, the dialog would be:
"Don't you have any socks?" – "No, we don't have any trousers. No socks are on the second floor"
But then the joke doesn't really make sense anymore.)
When we control oil prices by using reserves and trading agreements, does that cause people to fight for scraps?
How about when we subsidize silicon chip manufacturing? Did that collapse society?
You cannot, in a serious conversation, compare Soviet Union economic policies to modern socialist ideas. It's just silly.
"Modern socialist ideas" are basically the same ideas that were already tried in Soviet Union, just dressed in fancier words.
There's a simple answer for that: please look at communist Poland 1980-1989 - trying to counter raising prices with government intervention leads to supply crisis (since production is not economically viable anymore). Imagine all stores having nothing to sell, literally empty shelves, forcing common people to fight for scrapes.
