Good points. Yes I obviously agree that rules to keep capitalism less unfair could not be - almost by definition - implemented by neoliberals. Even Adam Smith declared that free and fair markets can only exist with the oversight of governments who keep the public interest as priority. BTW I’d push back on the idea though that new deal-type economies are completely dead as some countries especially those with strong labor movements still have aspects of fairness.
But your bigger point relates to growth. And I agree that this is a massive problem, probably the most important problem for humanity to deal with. But growth is not a UNIQUE characteristic of capitalism. Socialist economies also concern themselves with growth. What’s unique to capitalism is that the rewards of growth accrue to the private owners of the engines of growth. In socialist economies, growth can still be an economic objective but the rewards of growth (are supposed to) accrue to workers or society at large. Growth is not uniquely capitalist.
Anyway, this is getting a little bit off the OP’s original ask. From a definitional standpoint, I view the OP’s question about why lemmy users lean toward anti-capitalism as “why do lemmy users lean against private ownership of the means of production?” which makes sense coz we’re on a decentralized system, dislike centrally owned systems like Facebook, Reddit, etc. I don’t think s/he was asking why lemmy users are anti-growth. Although that’s an interesting issue to discuss too.
Guy is just a bad candidate. Whether it’s a lie or a screw up, who cares - he’s just not good. And this is the best alternative to Trump that the Republicans can produce. Vomit.
