DC of wealthy parents

[Rainingdogsandcats]

DH is a fairly high earner. My question is how do you keep your DC grounded so that they don't become entitled?

We are quite comfortable. Dd is at a Private school and DS will go in September. A lot of DD’s friends who were at the school from age 3 are in a bit of a bubble - one asked why people waiting at a bus stop didn’t just drive instead but both the dc have friends from a variety of backgrounds
We do treat the dc but with experiences rather than material things and while they get everything they need they don’t get everything they want.
We also make sure they know that they are lucky and not everyone has what we have. Seems to be working so far
