Assuming the question is serious... The actual story emphasizes several important lessons I think. The pigs that build from sticks and hay are depicted as being lazy- taking the easy, cheap way to build their houses. But when the wolf comes, their homes aren't up to the task of protecting them, in most versions costing them their lives.

The third pig is depicted as choosing to do the hard work of doing things properly. In the oldest extended versions of the tale the third pig is also shown to arrive early to events, which foils the wolfs plans. When the wolf finally tried to enter the house via the chimney, the third little pig remains level headed instead of panicking and manages to defeat the wolf soundly.

The lessons are to not take shortcuts, to do the hard work of doing things properly, to be prepared, to be timely (though this is omitted in most modern retellings), and finally to be calm and collected in the face of danger.

According to Green Jell-ÿ the moral of the story is that bands with no talent can easily amuse idiots with a stupid puppet show.

Their version actually expands the story a bit, it shows the first two were lazy,

Well, the first little piggy, well, he was kinda hicky
Spent most of his days just a-dreamin' of the city
And then one day, he bought a guitar
He moved to Hollywood to become a star
But living on the farm, he knew nothing of the city
Built his house out of straw, what a pity
Then one day, jammin' on some chords
Along came the wolf knocking on his door

Well, the second little piggy, well, he was kinda stoned
He spent most of his time just a-ganja smokin'
Hoppin' and a-boppin' down on Venice Beach
Getting paid money for religious speech
Built his shelter from what he garbage picked
Mostly made up of old cans and sticks
Then one day he was cranking up Bob Marley
Along came the Wolf on his big bad Harley

and the incredible lung capacity of wolves

Yes! It has always been a story about aerobic exercise and the importance of having a good VO2 Max. So you can use it to... *checks notes* destroy housing, I guess

Its been awhile since I've read the story but as I recall, the first two pigs built their houses poorly because they were being lazy and didn't see the need.

The story morale is more or less that bad things can just come along and wreck your day, so you shouldn't laze about when things are good, but should prepare yourself for future hardships.

The wolf is climate change.

I don't know about a wolf's lung capacity, but I could see it being a lesson about building materials. Of course, if a decent tornado comes along it doesn't matter what your house is built from unless it's underground.

If it's a tale about the importance of building quality then US-Americans must not know this tale lol

I read once that the tale of the three little pigs was modified from its original form to preach the Protestant work ethic and also as a form of Victorian-style propaganda, where the rich, educated landowner was the reasonable one.

It's a recommendation to boil your enemies alive.

I grew up with the version where the houses areade of mud, cabbages, and bricks. The moral was about over-indulgence.

It's a metaphor for weak Southern US building codes and extreme climate change.

I see it mostly as a tale to tell kids because they like repetition

also the moral lesson of not sliding down on chimneys
