I'll bite; Living comfortably, safe, well-fed and long; enjoying luxuries like vacations, media consumption, knowledge accumulation, etc. Being able to give your children a safe home to grow up in, an education so they can build up their own life instead of depend on you and your own accumulated wealth.

I had all this, thankfully, even without my parents being rich. They grew up in a time and area where they could still buy a decently sized house and have children on a single income. They struggled, but they made it.

Thanks to living in a (more) socialist country, taxpayer money paid for my education, allowing me higher social mobility than my parents. Ten or so years into my career, I've paid what was invested in me by the other tax payers a few times over already.
