I can see where you're coming from, but particularly for episodes the past year or two, the host has emphasized two themes worth noting: (1) the inability for models to really explain actual reality (as in how things really are for people), and (2) the importance of understanding that even if economic theory says on the whole things might be better, that they are often worse off for particular people.

Even to the extent that guest are oblivious to real world concerns (or alternate Ivory tower theories, which also happens sometimes), Russ Roberts is pretty good at respectfully challenging guests, and I feel like I at least understand where the guest is coming from.
