Many will quip that money doesn't buy happiness, but it certainly helps or some variant of this pithy phrase. Here's the real interpretation of these results: people need their fundamental goods satisfied, beyond that all you can buy are toys.
Fundamental needs are housing, food, education, a social life, a sense of purpose, a sense of control, and healthcare. Notice that nowhere in this is money mentioned. That means that society can in theory be organized around principles of universally delivering these foundational goods and values without needing to produce toys for the rich and we might all be happier for it.
