They SEEM to be very happy/content with whom they are and where they are in life. No desire to learn more or be any more than they already are. Fine. Different strokes etcetera and so forth. So why do they get so ticked off with others who are always wanting to learn more? Not everyone is suited to be a good student. So what? If you are happy with your path in life why keep looking at and attacking the paths others choose? What's it to youse?
