I spent weeks doing a full review of the literature which is outlined in detail here: https://80000hours.org/articles/money-and-happiness/. I largely agree with Stevenson and Wolfers and this article does too. One of their co-authors on this research endorsed our bottom line.

Money does make you a bit happier, but most readers of HN are among the top 5% of income earners in the world, so it's not the top priority for them, on the margin. You can get more mileage by focussing on other things. I also think affective measures of welfare are more reliable than evaluative ones. But it's a huge issue that I had to write many thousands of words to cover properly, so check out the full article and see what you think.
