That would depend on the alternative(s).
I like to think that a lot of the Solomani electorate are well aware of the shortcomings of their polity; with the Zhodani, that may be only allowed in the upper upper echelons, the rest of the dissenters get sent to Room 101.
No no no, there's no need to send anyone to a room.
The process is quite simple. The considerate Thought Police seek out those who are discontented. They bring them in for counseling. The counseling helps the poor soul understand what's making them unhappy, and how that can be rectified. In a more primitive society that might mean sessions with a psychologist, a psychiatrist, a life coach, a theologian, grief counselor, or any of a number of such service providers in a myriad of combinations over an extended period of time trying to teach some schmuck how their head works. In a Zhodani-based society, a single telepsychotherapist can seek out the cause of the unhappiness inside the subject's conscious and unconscious minds, help nudge a few attitudes and opinions in the right direction, then put a management plan involving their family, friends and work colleagues into play. The poor soul then becomes a contented soul, happy with life again, and is able to go back to becoming a committed and productive member of society. What's so sinister about that?!?
