I never said anything about communism, and neither did the GP for that matter, you can blame Jon for bringing that term to the table.
>My sense of meaning in life comes from navigating through this environment (our laws, rules, societies, etc.), and trying to make the most of it (and earn a healthy living) to provide for my family, and make sure that I and everyone I care about have enjoyable lives together.
> If we were in a communist society (and not one that's post-scarcity which seems far, far off), I wouldn't be able to do this
Why not? It's just a different environment, different set of rules, and different challenges. Some people navigated communism well and found meaning, many others did not.
The GP seemed to be using the label of capitalism to apply to sociopathic profit-seeking-for-its-own-sake, as opposed to the loosely defined economic and political model of capitalism. In that sense, what they're saying makes a lot of sense.
