You appear to be describing the difference between a communist society and a capitalist one.
The elders, and everyone, helps to raise the child in the "agrarian" because they realise the benefit acrues to all of society, and they have humanity; the modern way is to not do it because you can do other stuff that makes you more profit and puts you ahead of the others.
People in "The West" are much more involved in competing against other people rather than cooperating with them.
I don't think so, just trying to use the context of "agrarian village life" that the parent used. The point is that Capitalism provides a framework in which time, and particularly action, is linked directly to financial recompense and in which profit motive - rather than other firms of value - is lauded most highly. That moves away from community spirit, cooperation, fostering others, and towards greater emphasis on individual monetary wealth (and consumption that indicates such wealth).
