It's A Good Life is a story by Jerome Bixby.
It is definitely written in Third Person point of view, as the narrator talks about other characters, without him being in the story (First Person) and is not talking to someone who is in the story (Second Person).
It's not too clear if it should be cataloged as Third Person Omniscient or Third Person Limited Point of View, as the narrator seems to have more access to Anthony's thoughts and actions than to any other character (Limited Point of View).
However, Anthony has superhuman powers and can read everyone else's minds, so the narrator states some of their emotions and reactions (Omniscient) but without too much detail.
