You say you believe that your ability to get a degree doesn't correlate to anything other than your tolerance to debt or how rich your parents are.
But you clearly believe that your 2:2 in Physics (for Americans, a 3.0 GPA) is worth more than someone else's 1 in Urban Forestry Management (for Americans, a 3.7 GPA) so presumably you think that there is some variation in difficulty among degrees, and presumably you believe that smarter people will be able to get better degrees?
Nope, I believed that. I now realise it's total bunkum, as while one degree may be more challenging than another, from a hiring manager's perspective it's the GPA/class that counts, and little else, and value is in the eye of the beholder.
