I can attest to that - you never know what doors you might want to walk through in the future that require a degree to open (or are a lot easier to open if you have a degree).

Examples...

1) I moved from the UK to Australia last year. Having a degree made it a lot easier for me to get the requisite number of 'points' on their visa system.

2) A friend (from University) who just got a government job in Canada, had to dig out his degree certificate for job application process.

We graduated back in 1996 (21 years ago! gulp).
