You're comparing apples with oranges. If you're talking about a four year baccalaureate degree with a major in real estate I've got one.

I have got a Bachelor of Science in Business Administration with a major in Real Estate and Urban Development from the University of Tennessee. I graduated a number of years ago.

A post-secondary education in the study of real estate does not even talk about how to sell houses. A collegiate real estate curriculum studies things like corporate finance, government taxation and finance, economics, accounting, etc.

The College of Business Administration at the University of Tennessee years ago told us that the "Federal" Reserve was a "quasi public" (i.e. part public, part private) institution. The dirty bums didn't tell us they created money out of thin air.
