Of course having money can make things easier. But it is not - and should not - be the end all and be all. Should the parent who earns more "top" the parent who spends the majority of time with the kids, solely due to income? Where is the kid better off - with the parent who earns $100k+, then plants the kids with a sitter so s/he can go out and "play", or the parent who earns $27k, but spends their off time parenting the kids? The parent who has the nanny take the kid to the doctor or the parent who takes off work 'cause the kid is sick? No - really.
Yes, and I DO take this personally. For a variety of reasons, I make significantly less than my ex. But - WHO provided the cultural activities? And by that I mean taking them to museums, opera, philharmonic, ballet, other concerts, literature, etc.? ETA: zoos, psrks, the shore, etc.) No, not the "rich" parent. Maybe DC would like to explain to me why my kids are as comfortable in tux/gown as in tanks/cut-offs? Or can speak as intelligently on Nietzsche as on Harry Potter? Or Wagner vs the Dead? Just as examples. And yes, they are as comfortable with high-rollers as they are with Pineys. So DC can kiss my you-know-what.
ETA And WHO is paying for them to go to college (ok. one just graduated)? Hint: not the parent who told our youngest to not bother 'cause she wasn't really bright enough. Oh, note that he is a professor.
