I acknowledge your points. We did have a member who understood their language and he confirmed drugs were a problem even though they did not now use them. The constant use of their PC is only an issue if they are using it in a negative way. The internet can be an amazing tool for learning about the world but if it prevents people from getting out into the world and only become 'observers' of it then life can pass them by. Never leaving their apartment means they are effectively 'prisoners' to four walls.
Whilst the world of 'work' can often be a life of drudgery in a shallow job, more often than not 'work' gives people the ability to express themselves and of course, importantly, earn a decent living.
I don't see evidence of these people engaging with the world. They do drink a lot, they don't have a lot of pride in their appearance, despite Katya being blessed with the looks of a top model. Being in your twenties makes the world available and the future seem like a long way off. By the time your thirties and forties arrive the world becomes much more oppressive and the need to achieve becomes ever more urgent.
With regards to pets I firmly believe you can judge a great deal about a man by the way he treats animals. Taking ownership of a pet means you take on responsibility for their welfare and happiness. Fall short of either and a man falls short in humanity. What goes for pets also goes for fellow man. If he treats his pets badly he is more likely to treat his partners or others badly as well. Rusian doesn't appear to offer very much love and affection (sex is not relevant) to his partner Katya.
