It’s also probably rewarding for people who can put half the time into something and get 2x the result vs just normal people grinding slowly.

True but you don’t really mindlessly scroll through those communities, you mostly go on r/all or other popular communities for that. I used to watch a ton of content on r/videos but then some days I would scroll through the front page and just not find anything relatable to me. I joined the site pretty early, like back when it was mostly tech people. So to me the site got worse content wise but if that was the worst of it I could of accepted just hanging out in niche subs.

I just visited r/all and mostly just found American politics and low effort content. It’s just not for me personally.

The thing with reddit is you would scroll and scroll and not find anything interesting, just little blips of dopamine in sea of inane content. I don’t like everything posted on lemmy but I find it far higher quality overall.
