Years ago, I saw a study that said that there is as much child neglect and drug abuse in rich neighborhoods as in ghettos. Good parents tend to be middle class because, yes, you need to be able to feed the kids adequately etc but you also need to actually spend time with the kids and care about them.
Cher once said "I've been rich and I've been poor. Rich is better."
Certainly, all other things being equal, it's generally better to have more resources. But life isn't quite that simple and sometimes the price involved in successfully pursuing money involves a human cost.
If you can have lots of money and also have time for the children and also are a decent person, etc, cool. Some people pull that off.
Money can't buy you love.
