It turns out there are some great studies on this. Let's first acknowledge the "to each their own" thing.
Money doesn't make you happy. Period. Now, one can come back to the, "if you're broke how can you be happy, argument, and researchers have looked at that. Folks who live in very poor circumstances, say the Caribbean, or Central and South America, are significantly happier than the average citizen of the United States. They take more leisure time and spend less time obsessing about work in general. Work is a means to an end, not the end.
I'm willing to bet that the average poor disc golfer is reasonably unhappy. Their work is the end, it's what matters to them. Instead of doing something fun, you've turned into something where you have to make money. Sounds tough enough to me.
Please cite your sources before throwing around meaningless statements, unless you just saw the documentary "Happy" and decide to quote that...
