Albeit you do have to get into ludicrous amounts of debt to go to uni in the Us, so I'd say it's about even.
Although I'm not sure what the relative comparison of Us-UK degrees (and the rest of the world for that matter). All I know is that my exam results say I'm ****ing smart, my academic record says I'm ****ing smart, and my degree certificate says I'm very ****ing smart, so if some HR dickhead only wants graduates from Cambridge, Oxford, St. Andrews* et al they can shove their job up their arse for being so narrow minded.
*I don't know why St.Andrews was on that sort of 'top' list for applicants... their Cs department is very nice (It was just refurbed - I was up meeting one of the profs there a while back), but it's not AFAIK any better than anywhere else in Scotland. More elitism, I suppose)
