True to a certain degree, but you could also say that money provides greater autonomy. However there are also people who work because they choose to, rather than because they have to, and I doubt they all consider it a hobby. Some people may not need the money, but they need work to give them purpose, which falls in line with the article. It's a good article, though a bit too simplistic, as I feel that motivation is more individualistic and diverse than what's set forth. But I think the purpose was to set forth the authors premise in a straight-forward, scientific manner, so the simplistic nature of the article is likely unavoidable.
