I remember some years ago getting two credit card offers: one as an alumni of UCB and one as an alumni of UCLA (at a higher rate). I was puzzled by this; I had a B.A. from UCLA, but a masters and a Ph.D. from UCB. It didn't make sense that the more degrees I had the lower the interest rate; but then my ex translated; more degrees made me a safer bet and a juicier customer, so they were fishing for me with lower rates.
Like Billy said: them that's got shall have; them that's not shall lose...
