If I were you, I would focus on three things:

1. Raise your kids to be decent people - to have ethics, empathy, and compassion. ("We can buy anything" is likely to negatively impact this.)

2. Raise your kids to not blow it. They aren't going to have more money than they can possibly spend; they could still end up broke. Raise them to be responsible with what they have.

3. You are in the privileged position of being able to raise your kids to find out what they really want to do, and to pursue that. This means giving them a lot of things they can try early, and seeing which one floats their boat. (It also means not forcing them into forever pursuing what they liked when they were five.)

Yes, I am aware that 1 and 3 kind of contradict each other.

You could argue that raising them to be people who can make their own way without the money - that is, who can earn a decent income on their own - is part of 1, or 2, or both.
