It really doesn’t matter, from an economic perspective, what useful endeavor people are engaged in, as long as they are compensated sufficiently with currency (money) to enable them to compensate others, who do the things they don’t have talent and time for, in turn.
What really undermines efficient trade and exchange of goods and services is the rationing or sequestration of the currency (money) we use to mediate those transactions. Rationing currency is comparable to restricting access to reading and writing skills in order to hobble the ability to communicate.
We have some of that. It accounts for the fact that thirty percent of American adults are functionally illiterate.
Why is there an interest in depriving people of currency and literacy? It makes it easier to practice human husbandry, the exploitation of humans by their own kind to their detriment. (I use the third person possessive on purpose to suggest that the detriment accrues equally to the exploiters and the exploited. It is not good to exploit members of one’s own species. Indeed it is a risky business, since it can end in self-destruction. Even dumb organisms know better than to do that).
Currency and literacy are physical manifestations of figments of the imagination – expressions of our (higher) cognitive abilities. When they are misused, the very core of our humanity is degraded. People who do that should be ashamed. That they are not suggests that they are less than human. Otherwise, one would have to posit that humans are mere instinct-driven predators, who can’t even recognize their own kind — no more intelligent than frogs.
