> If anything communism gave you more social outlet and company then capitalism.
Communism gave you lots of (forced) company, but it also banned the previously existing communities.
For example, the Scout movement was banned, and the communist version - the Pioneer movement - was made mandatory for kids instead. Seems like "okay, if it's pretty much the same thing, only more kids are involved, that's great", except it wasn't the same thing.
First, because mandatory fun is not fun anymore. Instead of kids who enjoy some activities, and adults who want to try some fun activities with kids, now you had a classroom full of bored kids, with some bored university student who was assigned to the task, doing the most boring version of "fun" (such as playing the same simple game at every meeting) in order to avoid punishment.
In theory, it didn't have to be like this -- there was a lot of thought put into it; the communists have printed literature for the Pioneer leaders, like encyclopedias of games (I know because I have found a few such books in a library) -- but in practice, no one cared. The leaders didn't care, because they didn't volunteer for this, many of them probably didn't even like kids, and they knew the kids don't have an option to leave anyway, so why bother, spend one year doing the "Party task" and hopefully never again.
Second, because if something is mandatory and universal, then instead of an escape from reality is become just another part of the reality you want to escape from. In the Scout movement, you go somewhere else and meet with kids from other schools. In the Pioneer movement, you have the mandatory "fun" with your classmates, probably in your classroom, so it feels like yet another school lesson.
And for the adults, you have the "workers' collective" at your job, and it often expands into your free time. But if you instead try to regularly meet with adults who have similar interests but are not your colleagues... it will probably be investigated as a suspicious activity. (And then you had family, which was the only collective outside your work that wasn't treated as suspicious.)
