My wife’s father helped build a tech company that is now publicly traded in a non-US company. They aren’t super, super rich but probably around $20mm+

It was difficult getting her to understand the value of a dollar. She has very expensive taste - luxury hotels, fine dining, name brands, etc. Her expectation was that I should make enough so that she could buy those things. During our first couple of years of marriage, her parents would give her a bunch of money so that she could. Instead of saving that money, we blew right through it. We then blew through our savings and the wake-up call was one day my telling her we had to get a loan to start paying for stuff. Her parents stopped giving us money (which I’m grateful for).

It’s been a tough transition for her to live on a upper middle class income. She complains about me not making enough money, but I’ve emphasized happiness through other aspects of our life. The more she feels loved, the less she frets about material things. When she’s angry or feeling lonely, I notice our credit card bill increasing.
