[WS:] Definitely true. I think it had something to do with union/party membership, because not every proletarian was that way. And it was not just in the USSR. Case in point - several years ago I was on an Amtrak train en route to Harrisburg, PA - there were not that many passengers, so the conductor engaged in a chat with me. He was an old union guy - not only expressing the qualities that you mention but also bemoaning the generation of new workers, including his own son who was a truck driver, for their individualism and anti-unionism.
You need working class institutions to maintain working class consciousness. Individuals simply won't do it on their own.
While we are at that, this summer I went though some family records and I found papers left by my grandfather. The old man was in St. Petersburg in 1917 playing some (minor I suppose) role in the Bolshevik party for which he later received a medal. He was a card carrying dues paying member of the Communist Party almost to his death - the dues stop a few months before his death.
