I am curious what kind of jobs you refer to with “busy work positions”.
Look at the entire supply chain. For instance, a company makes mining equipment, a company mines, one processes etc... They end up making some piece of crap sold on Temu, or a phone that people use to watch TikTok. Between there are oles like IT that facilitate the sippy chain to more efficiently lead to nothing very great. As fast as advancement of humanity goes, or is just busy work. But if the roles were facilitating Human excellence, the same role could be very valuable. As it stands though, most are not.
More creative tasks. If that was to increase human excellence, then it is valuable creativity. If it is to entertain so as people avoid doing valuable work, then it is a coat, right?
