Destinharbor said"When did higher education turn into vocational training?" I totally agree with you on this but unfortunately, the answer is : About the time of Reagan. People became production units. That is also when the income gap started down the wrong path. But we live in today's world. I have a high disdain for most MBA's (the degree, not the people). I think it teaches you modeling and tax loopholes. BUT, it does also teach some accounting and management, two things you'll need if you want to be the head honcho of anything. I don't know what a graduate degree in sociology teaches but like said, philosophy is for teachers. I'd think long and hard about whether you want to work alone or manage people to an end. If you want a management job (non-profit or other), you might want to add in the MBA. Even a one year degree. Many, many people think it's a sign of serious if you want to run a group. PHD is for teachers.
Sociology has several different sub-groups, but mostly it helps prepare for working with people of many different backgrounds such as those who suffer from addictions, abuse, marital conflict. It is the Study of Society as a whole (where as Psychology is the study of the Individual).
When looking at those who suffer from addictions, we do not blame the addiction on some cognitive problem, more on less of the societal factors for which allowed the addiction to begin. Such as the policy paper I wrote on the effects of increase of Alcohol Advertising, and the increase of Juvenile Binge Drinking.
