Economists are the least moral people from any field. My economist friend agrees. They see money as a number, not as a resource people need to survive.
An economist may agree with the statement: "A starving honebee requires more honey to recover than it will produce in its life. Therefore saving it is a waste."
What the statement lacks, is context. Why is the bee starving to begin with? They eat nectar from flowers. So there aren't enough around. Humans are good at mowing their lawns and placing tiles in their gardens instad of anything useful. Another part is, where is their honey? The bee's life saving they use to survive winter? Who took it? The humans. And who has the audacity to define the life of a single bee by it's ability to produce honey? The human.
Now swap worker bee with working class, human with the rich, and honey with money.
"Oh these people require medical aid? As if their labour is worth the investment in ther health!"
Remember, any person providing a service to society, is a valuable person. Be it store cleric or garbage man.
And horses, most zebra species, elephants and elephant seals (by crushing the newborn. You have to see those 4tonne blubberfucks run at a female who just gave birth. It is glorious), rats, mice and many other rodents.
Some bears. Black or grizzly bear if I remember right, kills 14 cubs a year on average. They then stalk the female till she ovulates, mate and move on to the next target.
Primates in general. Mandril alpha's sometimes kill their own out of aggitation. Chimps cannibalize orphans if the mother dies/gets killed. Sometimes female chimps are killed for being too assertive, or struggling back too much when males force mating.
Cats and tigers kill their own because they can't discern nor care about decerning whose cubs they are.
Kangoroo's don't kill joeys per se, but they choke the female to death sometimes. Really just because they are as horny as they are aggressive. Females are always pregnant. When their pouch is already occupied, the embryo goes into diapause. Slowing down its development. A queue for the pouch if you will.
It's only useful to the male. But energywise, it is detrimental for the female and the species as a whole.
In other words. Men are fucking awesome. We are much more like birds in our reproductove strategies. We form a partnership, and work together. Men and women developed ways to cooperate together. That's awesome. It's just that the chances of unwanted behaviours, come from "old habits die hard."
