Forget about living condition, corruption or censorship, let's talk about police state.
First, you couldn't just choose where you wanted to live, you needed to get government approval for it. Spending a few nights at your relatives? Had to register with the local police department.
Talking about local police, there was usually an officer responsible for a given residential area. He/she knew every member of every families living there. People, usually one per family, were "encouraged" to attend monthly meeting where they were reminded that there were "evil" forces who did everything to undermine the party and the government, and that was everyone's responsibility to report any suspicious activities (I did hear that a lot post 9/11 in the US, but only at public places, for unattended packages. Still it provokes a lot of memory).
Promotion at work? well, you'd need a recommendation from the head of the block where you lived. Make sure to be on good terms with him.
Wanted to visit another country? You couldn't, unless on official business. As the result no one could have a passport until their first trip abroad.
The sad thing is, most people considered all of that as normal, if annoying, facts of life. No one cared about police listening to phone conversation or checking (snail) mail. Because that was their job, of course. In fact, where I lived such policies were overwhelmingly supported. When the Berlin wall was demolished, I remember asking my dad why Soviet Red Army let such thing happen. Why not invade and crush "the enemies". You got brainwashed since very early years.
Where were the Snowdens you might ask? none existed, and if they did, there'd be no NYT or Washington Post or the Guardian to report on it. Newspapers closed up shop for much less serious incidents.
So bashing NSA all you want, they're hardly angels -- never broke any law evar! but the next time you try to pull a smart-ass, be damn sure you know what you're talking about.
