FWIW I have a friend from Azerbaijan who saw a lot of the USSR as well. I don't know the details, and there will likely be people here on HN with first-hand USSR experience who can tell me why my memory makes no sense. But his story was that there was money but you couldn't use it for much, except train tickets. They saved it up and then took epic train trips through the USSR, once up to Estonia and once east towards Kyrgyzstan (not sure they got that far though), stopping in every republic along the way.
His parents were a craftsperson and a high school teacher. Don't make assumptions about strangers on the internet.
