Ultimately I plan to draw a clear distinction between my money and theirs.

Do this publicly at restaurants with loud, evil cackling ;D

I don't imagine my kids will have 'expensive tastes', to be honest I think a lot of that spending comes from a place of emotional insecurity.

ooh, this is really interesting and I would say that you are right. I think I have seen this from the "poor" becoming rich, and the "rich kid" trying to feel on even footing with parents.

something to think/ write about perhaps :)
