Strong connections with kids are the most important thing, but it cannot be the only one. It wouldn't end great neither for both parties.
Note that I am not talking about earning a living and thus necessarily sacrificing time doing that and showing your kids that sometimes you have to work hard to survive in a decent way. I am talking about the parents who outsource their children to childcare to work to pay off the loan on their third car and newest iphone and tell you that they have no choice.
