My growing up was like Smurf's. My dad traveled and worked long hours, at times, but I never felt less than because of it. He put in quality time with us. He came to every game he possibly could and I always knew he was my biggest fan.
As a parent, I carry both mom and dad responsibilities and stress about $$ all the time. I make a pretty good living by today's standards for a single mom but it's a heavy burden to carry. I've never missed a game of my son's but if I thought missing a game here and there would significantly benefit us financially, as a family, I'd probably do it.
That being said, I strongly believe that we should not forgo that quality teaching/ bonding time with our kids for a difference between 1.5 and 1.51 million, for example. Some of the most messed up kids I work with in child psych are from the wealthy homes. They have everything they could possibly want and yet the only thing they really want is a parent who puts the time in. It's sad when it takes a slashed wrist or a pseudo overdose or suicide attempt to get mom and dad's attention and then it's off to the couch to fix the kid, when the kid is a product of their environment. Society for kids and teens is really tough these days. They may graduate debt free but you have to get them there first and give them that solid foundation of who they are and that only comes from time invested and a strong relationship with your children.
/soap box and all, of course, imho
