I think the phrase "the best labour saving device is money" is partly true.
For me and my family having enough money has meant living in a good sized house in a nice area and being able to educate our children privately. We've also supported them through university with no change in our lifestyle.
Because we pay people to do boring shit like cleaning, decorating and gardening we have quite a bit of leisure time and the money to do nice things like eating out, which we do as often as we want.
Whenever something breaks (washing machine, dishwasher and fridge in the past few years) we just replace it.
When our mortgage increased we could afford it. Likewise when gas and electricity prices went up, it was annoying (£500 a month at one point) but we could still pay. We do have a mortgage so we're not rich but we are definitely well off by my standards. And it makes our lives easier and therefore happier.
Of course it doesn't insulate us from illness, bereavement, sorrow or tragedy. Our children have had some mental health issues and we've had awful things happen in our lives. But I'd still rather have money than not.
