Spending money on those things takes a lot of effort though, maybe they just had ADHD and didn't want to think about all the ways they could spend money? Typically it is much easier to not spend money than to spend money. A trip to a foreign country is more effort then a local vacation, an expensive renovation is more effort than just living as is etc. A big home is more effort to clean, a big yard is more effort to manage, a big car takes more work to keep reasonable etc.
