Some people could argue that knowing that the earth revolves around the sun won't change their life or help bring money into their home. If a guy isn't interested in astronomy but likes cars and can fix them then that's fine and it's probably of more value to society than if he is well read, is a constant student and doesn't contribute in anyway to society. Hey somebodys got to serve burgers at Maccas too. :-)
The whole basis of civilisation is that everyone has their role. People can't be expected to do every role the man who farms can't be the doctor too. The opposite of this is subsitence living which leaves no time for science and other developments. It does nevertheless surprise me how more and more people have a lack of general knowledge but it doesn't seem to be of any detriment to them.
At some social get-togethers I've got little to talk about, I can't talk about the footy or the latest reality television hit, if I started talking about astronomy I'd be standing alone in the corner after a while. It makes you wonder who the real losers are sometimes. Some of the most narrow minded, uninformed people I have met are my superiors at work, earning heaps of cash and all they've got is the 'gift of the gab' but are as thick as two short bricks.
