I promise you, if you put that $30/month into your own IRA, you’ll make her a lot happier when she doesn’t have to support you when she’s grown up.
The problem isn’t spending a little to make you or your family happy, it’s spending for consumable things today, that’s going to put you at a huge disadvantage later.
I get it, I have two kids, it’s fucking expensive. But you know what’s even more expensive? Taking care of old people.
