The intention wasn't to compare wealth with happiness, but was to draw a comparison between two different domains, with one that some people can objectively understand. The idea being that in finance, you can for example buy an object (collectable, gold, virtual currency, ...) and it just sits there collecting dust. It may go up in value, but to realize that value you have to sell it, then you don't have it anymore. Whereas investing in something that generates value (dividend paying stock, education, tools for your business, ...) gives you returns without having to sell it. Although in most cases you still have to put in work (you have to work at education, and work to utilize it, and you have to apply work to your tools to generate value). Same is true for other non-financial areas -- it takes work to make the connections and maintain friendships, and there is effort that continuously goes into the processes that give you rewards for those friendships (you can't just be one-sided, take but not give, and there is not magic formula, you just muddle through it the best you can).
