Every parent to be should read and adapt this approach

Every government should read and adapt this approach.

You mean, like, "To each, what they need; from each, what they are able?"

The problem is that there are several stable equilibriums to that proverb:

Everything can be taken from a slave and dead people need nothing.

To rephrase in a less hyperbolic manner : desire is unlimited, and you need force to extract work from the unwilling.

Of course, the unstated subject of “from each” is always you…

"There were many unpopular parenting rules I followed as a young mother. But my No. 1 was: Don’t do anything for your kids that they can do for themselves."

The three great virtues of a parent: Laziness, Impatience, and Hubris.

-- almost Larry Wall

This is literally my #1 rule and it's so blindingly obvious I don't understand why it isn't just common knowledge.

It's also not unpopular at all in my experience, especially with kids that grow up on farms and ranches (we're basically rural) where you have to go do hard physical labor regularly just to survive

Funny that this is being presented as "unpopular." It's very common advice from child behavioral therapists. What kids want is freedom; but what they need is responsibility.
