That's definitely true up until a pretty obscene level of wealth, but there's definitely a difference between basing all choices around money, and basing major choices around money.

For example, I no longer scour the grocery store for the cheapest available option for every item I select. I no longer have to spend months finding the best value for a pair of shoes, a piece of furniture, etc.

Basically, if I spend a couple hundred dollars too much on stuff one month, I'll hardly notice it. Whereas, when I was poor, that was the difference between making rent or not.
