Darrin Stevens was mentally challenged

So Kath and Diana have been watching re runs of the show Bewitched. For those of you who don't remember the show is about a witch named Samantha who marries a mortal named Darrin. Here's the part i don't understand. Darrin was pissed off everytime Samantha used her witch powers? Seriously? Darrin what was wrong with you? I would love if Kath had witch powers. She could magically make piles of money appear for one thing. I could quit my lousy job. Darrin worked in a shitty job. His boss Larry Tate fired him almost every episode. Hmm what else could i get a witch wife to do? Want to take a vacation? A snap of your finger would get you there immediately. Hmm i feel like eating a cake. Poof! A cake magically appears. Something was wrong with Darrin man. If my wife was a witch i'd be living it up with an endless supply of money and cake. I guess thats why i don't write tv shows.
