We need to consider what's good for society as a whole, always keep that in mind. Part of what we need to do is have a job for everyone who wants one. In addition to keeping up our infrastructure, it makes sense to make investments in arts, music, history, education, experimentation. These investments will pay huge dividends, so it makes sense to make them collectively (i.e. through taxes). There should be no such thing as getting a degree in something worthless. If your passion is ancient literature, and you are willing to work hard at it, then society should provide for you. The capitalist model completely fails at this and it's to our detriment.
