This is true although a significant portion of increased quality of life can be purchased using wealth. Just like "money can't buy happiness" which is true, it can certainly drastically increase the opportunity of happiness. A significant amount of quality of life improvement has happened as I've grown wealthier over the years. In the form of time alone, I have more personal time to do things I want to do rather than being forced to work for someone else to meet basic needs. I have a fairly large yard and used to maintain it, it took a lot of time and wasn't something I enjoyed (just the final aspect of it). I now pay people to maintain it, I enjoy having a well kept yard by simply paying for it. When I had less wealth, a significant amount of brain cycles was spent looking for ways to reduce or optimize some cost around something. Now, unless I see a big price difference to where it may impact other aspects of my life, I don't fret a few dollars here and there. When I had less wealth, even with healthcare, I'd probably push through work vs taking a day off because the risk of not having enough sick + PTO days off should I get more sick. Now, if I feel sick, I don't hesitate to use sick leave. Wealth also affords me more overall bargaining power in employment negotiations. Having enough "FU" money let's me dictates my terms with more authority leading to more enjoyable work environments. Overall wealth allows me to pay a lot of things away I'd otherwise have to do. It also affords me opportunity to do things I want I might otherwise not. I take more international vacations since I became more wealthy and it's been great, just returned from a nice vacation. Part of that trip involved splurging on some nice dining options, paying for luggage delivery/management, and having more comfort in my transit options. With my new found increased time wealth bought my, I exercise frequently and my health has improved or at the very least, my overall feeling throughout the day. There are a lot of things people get diminishing returns of in terms of quality of life vs wealth where it doesn't matter. My bed is just as comfy, I've been fortunate enough to never be short on food, and so on. If you're single, it can make you more attractive especially to women but it's not everything, physical looks and personality are still more important to most people (at least the people I'd want to meet). So while wealth isn't a direct indicator of quality of life, it's certainly correlated and I'd argue for many, a strong correlate. It won't get you everything, some things wealth won't help you with (I still have to exercise my own body, I can't pay that effort away but at least it enables me to do that more readily and on my own terms, for example).
