The Soviet economy was somewhat surreal and it is difficult to explain it well to the Western audience. Including vacations, vacation tickets («путёвки»), summer camps, sanatoriums and the like. I still remember some parts though, so if you are interested in how it worked, I can answer your questions. Most definitely it wasn't all that rosy.
One anecdote for not all rosy:
My father is permanently traumatized because he had to get his tonsils removed when he was young and they didn't give him any anesthetics.
