I've always had a decent salary so never worried about affording basics or paying bills but when kids were small and had daycare costs, things were tight.
However, since then my salary has gone up and certainly enough to live on comfortably. Plus, sadly, both my parents died relatively young (at end of working life but not really being able to enjoy retirement). Since they were divorced and neither had remarried, my sibling and I inherited their properties plus their other business invesments which had done very well over the years.
As a result, we live off our salaries and the money we inherited is invested. We made some pretty good (and also lucky) invesment decisions which mean that the money is generating additional income for us. Basically six figure annual household income and now million+ in investments and property.
So I don't worry about money at all. If anyone in the family needs something we can get it. We don't live extravagantly - one 13 year old car which does the job for us, no flashy clothes or jewelry or electronics. I don't see the point in conspicuous consumption and we don't mix with those type of people (plus we don't talk about money so only a few close friends actually know how much we have)
What's important to us is being able to pay for kids' education, for them to graduate uni with no debt and do whatever further training they need, being able to access private medical care when my child had serious mental health issues and NHS provision was shit etc. Eventually, we plan to use the money to help kids with deposits for houses and for own retirement. This is all a massive privilege and I am keenly aware of this.
I will say though that I look enviously at people my age whose parents are still alive and healthy. I'd give up all the money I inherited in a heartbeat to have my parents back. So in that sense money doesn't buy happiness. The money I have came at a huge cost. But, that said, my parents would have died anyway and it would have still been shit with or without money, it's not like I could make that choice
