There are of course many people who's disabilities make consistently showing up to do anything very difficult. Like my Aunt who's cancer treatment left her with peripheral neuropathy that comes and goes like the randomness of the wind.
And then we have the un-nurtured and even rejected interests of gifted minds, like musicians, artists and mathematicians, who's gift is deemed a pointless frivolous indulgence rather than a possibility for new thought for the species of man.
We all hold duel beliefs, that the exploration of these lines of thought are noble persuits worth lauding, and a pointless endeavor that should be met with outcome of poverty, pain and struggle. Which in some ways further silos off the realm of art math and music, to only be the playground of the disconnected children of the wealthy. The thoughts that spring from their minds are allowed to shape perceptions.
TLDR: Some people can build a better world by plowing the soil, building a machine, cleaning and feeding the new generation, and some are not made for that. It is unnatural to expect such incect-like behavior from man, while also limiting the hive's ability to better itself by muting the minds of tomorrow with tedious work.
