Those tend to get overlooked by people longing for the old days.
can parents support their child that is an artist with their income? or the state knows everything about the artist (her age, fit to work so on) and will compulsorily draft them to work?

Could you provide evidence for this?
I know my uncle was supposed to go to one company but then that didn't work our for some reason and he had to look for a job himself, which was supposed to be rare. That would be early 1980s.
There were also a plenty of 'underground' artists, who had a day job of being a book illustrator, and did some stuff on the side, which they only would show to the close circle.
Your description of artists' life is pretty simplistic and one-sided. There were some people who did propaganda posters, but there were many things that existed outside the political domain, from book illustrations, to paintings with less ideological overtones, to working in theater. There was also Soviet cinema and animation, which would hardly be seen as only a propaganda vehicle, there was a lot of very nuanced works, which raised important questions. A lot of good stuff was shelved, or circulated underground of course.
It is an interesting film in general, and in context of your comment from the politics of art perspective -- it starts with a Nazi lecture on the "degenerate art" of 20s-30s, to art class lectures in Communist times, and ends with the equally ideological forces dictating "what's art" in West Germany (where are hero finally achieves fame and fortune.) It's East German variety of old regime/new regime but likely will resonate at some level.

We all have family or friends who were artists before 89. The state arranged structures for artists to have jobs and even subsidised it strongly, so working people could afford to experience culture.
