Well, I'd question whether "communism" was what happened in the Soviet Union and the satellites. But that's a side issue.

The point is, I think there is much wider agreement about what is right and what is wrong than is often recognised. I think most people do believe that the way the good things are distributed is unfair, with some people getting a lot more than they deserve, and some people getting a lot less.

Where the real disagreement enter is when it comes to working out what can and should be done about it. For example, there's no contradiction between saying something is bad in itself, and bad for society, but that certain ways of trying to make things better will introduce fresh injustices, and change the way people behave in various unintended ways, and end up making things worse.

And in the same way it's possible to believe that something is good, both in itself and for society, but that there's no way of preserving it which won't end up making things worse than they otherwise would be.

And that's what politics and political arguments are about - working out both what is desirable and what is possible. And there is room for enormous differences.

But whichever side we end up on, we should always watch out for those people who come across as allies, but who are really enemies. Thieves and robbers and predators, for example, even when they employ good bent accountants. And politicians who exploit the situation to feather their nest and make a comfortable living, and care for nothing beyond themselves.

Insofar as songs focus on instances of injustice, they are focusing attention, and raising questions. Finding workable answers to those questions are what politics is supposed to be about. "Which side are you on?" is always a fair question, even if in some cases the answer for a person might be "On some other side that you haven't mentioned."
