You could NOT travel anywhere except on very exceptional conditions and only in the communist countries of the communist block. Also being paid very poorly one could not really afford any travel!
You would not own anything and that did not make no one happy! The land, the house nothing was yours all was owned by the state.
You could not aford to pay for a car and you could theoretically buy a car in almost a lifetime using a social credit system which was bad and poorly implemented;
grocery stores were empty;
food was bad and very scarce;
We were getting in a line, in a row, the nights before when we had a rumor that the delivery trucks will come the next day. All the food was sold, based on a food ticket from the truck and the food products were never reaching the shelves in the grocery shop;
One family was only allowed to have only 1 bottle of of cooking oil and 1 pack of butter per MONTH, taken that ticket IF these would be available at the grocery store and if you got the ticket!
The quality of any product was very bad, but you would not notice because there was nothing to compare to;
The people had work, but most were just doing really just the minimum to get the payment which was not much and the quality of work was very poor in almost all industries. Also understand the timeline. In 1980's the kind of jobs that people worked today may not exist at all because of technology! So if you would have communism today, most people would have very limited types of work! (You will see soon... Say Hello to Artificial Inteligence!)
Most people were very corrupted, because they need to EAT so a lot of underground market was taken place for those who dared because:
IF you SAY or did ANYTHING which was not inline with the communist party you would be incarcerated and beaten to death...
I will stop here as there are so many other important aspects...
Lived in Romania for almost 50 years and I know how communism is so NO, THANK YOU!
**Also understand that even if you would have communism today it would not be the same type of communism as the TECHNOLOGY CHANGES EVERYTHING! **
I invite you to learn more about China's social credit system and WeChat app!
