“If only everybody could be motivated to 'work' for the good and furtherance of society while accumulating modest individual wealth. Too many are motivated only by the desire to accumulate ever greater wealth and to hell with society.”
Well. I can see the point. Too many are too selfish. The world would be a better place if people were more concerned about society.
Now the question arises: what actually society is, after all? You may have seen millions of people, but you haven't seen society yet. You may have heard thousands of opinions on what society is, but society alone never speaks for itself. Rather, you can hear a lot of political activist or propagandists claiming they know what society needs.
To be sure, there is something that may be called society. Millions of people sharing the same country, the same laws, the same economy, must inevitably share similar problems, wishes, preferences. Yet you can hardly claim you know what it needs. Each of the huge number of people is an individual with his or her own worldview. Each is in a unique situation. There is no common recipe for happiness. I do not know what is best for other people. Nobody does.
I have no objections against voluntary community work for “society," whatever it takes. Actually, I've done some non-trivial amount of unpaid work pro bono publico. However, I'm strongly against forcing anybody to work for free. That would be tantamount to corvée, which is an unpaid labour owed by a vassal to his feudal lord.
There are many people who propose that other people should do more for society. Their intentions may be frank and honest; usually, they do not realise that they propose a re-introduction of feudalism. Actually, every kind of forcing people to do something for “society” boils down to feudalism. In the socialist countries, they ended up with quasi-feudal oligarchs (as in Russia) or, worse yet, with a full-fledged feudalism (some Central Asian post-Soviet republics, and, infamously, North Korea.)
This is why socialism and feudalism are equal: both are based on forcing people to work for “society”; while the definition of society depends on the judgment of the ruling feudal (socialist) class.
I am willing to do something for free for what I believe may be a common good—but if you want to coerce anybody to anything, please count me out. The world would be a better place with less compulsion.
There is no difference between feudalism and socialism.
