I think the point hodgehog was trying to make is that overall wellbeing increased. Famine is down, disease is down, wars are down, security up, well-being up. Innovation overall benefits everyone in the long run. Global scales aren't the problem---goods once reserved for the wealthy are being copied and produced at markedly lower prices, with examples such as EVs and drones. I realize that "overall" is doing some heavy lifting but I think it's rather unreasonable to dismiss the entirety of human technological progress as only benefiting the elite.

only if you assume capitalism is the only stable economic system. without wealth differences there is nothing other than your own abilities that can make access to tech unequal.

Not really, western countries were doing a lot of that in the 20th century (amongst themselves, anyway). Then the 80s happened.

Or what, do people think that the boomers were all that good, that they genuinely earned everything they got? The generations before just worked out how to govern properly.
