Materialism is a character flaw that is not made any worst by a better education. In fact, I would guess that if you are busy studying and working hard to learn you don't have time and energy to worry about what the latest toy is that is being sold. You also have your mind on more important things than just trying to impress someone with your wealth. The other thing, the Society worries about is the time that is taken away from the ministry if a person has a carreer. I know of many professional people who work at home on a part time/ full time basis, with no traveling to an office. These jobs are paying very well and the employers are happy to have such skilled people stay with their companies working from home. Many witnesses who have gotten an education are enjoying some of these benefits and actually are spending time in the ministry, what is sad, is so many others who never got an education have to work for much lower wages, which requires often times working more than one job just to make ends meet. Many young ones start out pioneering out of high school only to end up woking more hours and having less time in the ministy than those who they critized for getting an education. So many things wrong with the Society's slant on higher education, it isn't even funny anymore, just plain sad.
