It could also be interpreted as a criticism of Libertarianism. The first two pigs didn’t go by any building codes, and instead decided that they wanted to build their shelters out of inferior materials with substandard protections against high winds. The third pig made sure that his dwelling met hurricane standards, and was saved. The story doesn’t go into the reasons why pigs #1 and #2 chose inferior building materials, so it could be interpreted in a number of different ways. It doesn’t HAVE to be about economics. It could just be that pigs #1 and #2 were big fans of Ayn Rand and reaped the whirlwind as a result.
