I think it's just an elaborate plot against the daughter. Fast forward 6 years...
Daughter: "Daddy, I'm 16 today! Can you buy me a car?"
Father: "Well, sweetie, I would...but daddy can't afford to now, because you decided to take after your mother and be an unbearable mommy part six years ago by nagging about how I'm never home. So instead of making tons of money to buy you a Maserati, I decided to show up to your worthless recitals, games, and other shit that would never amount to anything, because in reality, you'll never learn anything that will allow you to become a self-sustaining adult, as you ultimately just plan to suck off my financial teat for as long as you can, before you decide in a hormonal rage that you hate me, want to leave the house, and get impregnated by a transient drug addict."
