You make great comparison with communism - Ive lived through it.
You know where that lead to? Very, very small group of people (politbyro, but you can call them papacy aswell), who knew each other held responsibility for redistribution of wealth (social justice, but could be called salvation) in the name of the state (god).
These men were very close to historical definition of demi gods. Tasked to administer collective means of production and development, since private property was not really an option. At different time periods taking or protecting lives seemingly at whim.
Democracy, that westerners taky for granted is quite fragile thing, tied intimately to the relationship between means of production and its owners. Take common men out of this equation and their role in the political system will diminish aswell. You are right, you would be probadly well fed and clothed in such system (as it will be obligation of upper class in such social contract), however ultimately you would lead a life of pet in a nice cage.
I am not forcing this view on you, just sharing my experience and perhaps hoping it will make you think.
THAT IS WHERE THE ANSWER LIES!
The problem is in fact what you've lived through and what USSR knew has never been communism. Yeah we called that communism but it was not. It was a simple and plain oligarchy with a group of people having all the powers.
But you'll tell me, it can only become this. Socialism and communism can only lead to that as the state will take more and more and "redistribute"... But only a few people will decide how it is redistributed!
WELL NO!
There is a solution now! Direct democracy.
Imagine this: a country with high taxation where the people rather than elected a king for a few years who will decide everything, people actually vote directly the laws and the budget.
Then there is no politbyro as you say. Because we all give and all decide equally.
That can sounds as an utopia but... Technologically it's fairly easy to do. What is really opposing that?
