What is your opinion of Stay-At-Home-Moms who pamper themselves?

My wife's main goal in life is to be a SAHM. It's never been one of my ambitions to have a SAHWife but she's been very insistent about the benefits to our children so I've reluctantly agreed. She's been a SAHM off-and-on for awhile now. She'll occasionally get a temporary job to help make ends meet. But when she goes back to being a full-time SAHM, that's when the pampering begins. She sleeps in every morning and she doesn't get much done throughout the day. I thought the goal was to take care of our kids, but her main priority seems to be taking care of herself. I wake up at 5:30 every morning, drag myself out of bed, get ready for work while watching her snooze, and then go out in the cold to go to work. Meanwhile she wakes up around 9:00, casually fixes her breakfast, takes it easy for awhile, then gets our son up and plays with him. Her day seems to consist of playing with our son and maybe one chore. We usually go for days without the dishes being done. And I'm often the one to fix dinner for everyone after I get home. Meanwhile our son doesn't know how to relate to other kids his age. And he doesn't seem to be benefiting THAT much from having his mom home all day. I guess I'm just having trouble seeing how this is benefiting anyone but my wife. Am I being suckered? I'm not enjoying living like paupers and shopping at Goodwill just so that my wife can pamper herself. Am I the only husband who feels this way? Someone help me to understand the benefits of having a SAHM. Thanks!
