Hmmm, I kind of agree with what Wildpatch said. More things do come in to play when you are rich, not that I have first hand experience of it!
I started pondering WWW's question, and while my dds prob won't need private education (the state round here is perfectly adequate) I started thinking, "but if I'm loaded, I will have to send my children to private school", and "I'll have to upgrade my car every few years", and "I'll have money to spare so why not get a nanny and a cleaner and a gardener," almost as if money makes you think more idly and more inclined to throw money at things rather than just get on with them.
I have a (v v loaded) friend who despite being a SAHM with two children at pre-school/school still has a nanny to help with her (incredibly docile) baby. And she has a cleaner, gardener etc... Some days when I'm hanging out in her gracious drawing room it seems as if she has a full-on army of staff there to assist her! She comes from a background where these things are almost expected. God forbid she should have to cope on her own like the rest of us!
I imagine her outgoings are extortionate and how much money she has left over I don't know (more than me I bet! )
