Why degree mills center so hard in post-graduate degrees?

[elcastor21]

I think it's because of people's psychology. Graduate degree, especially one which would provide sense of belonging to a privileged, "elite" group, is more desired than undergraduate degree. People are easily manipulated with their emotions. That's why some people are crazy if they see an "MBA" for $300 even when they know a real MBA for top-level executive can cost $100,000 and more. They want to be able to say "hey, I'm just like those CEO guys from F100, I also have an MBA" at least to themselves. Can't blame them for their feelings, but they are lying to themselves and are manipulated into buying a piece of paper because of that.
So because of that the diploma mill's revenue is likely to be higher, as more people would buy an "elite" degree than just a "degree.

I understand it may be for the status, but, what would a buyer of such "degree" would answer when HR or anyone ask them about their bachelor, how did they got an MBA without having one (I understand there are cases like the UK's Qualification Framework allows such things, but most people don´t)

Also, there are perfectly legitimate MBAs for less than $1000, for starters ENEB/Isabel I, for those curious lurking here.

EDIT:

but they are lying to themselves and are manipulated into buying a piece of paper because of that.

I think that answers my question...
