Depends on why you need it. I initially thought I wanted to be a teacher when I left school. Teachers need degrees so I did a languages degree. I even applied for teacher training but quit half way through the year as I realised it wasn't for me. I now work in the civil service and have climbed from the bottom up to a senior grade. Many people in the CS don't have degrees, so yeah, considering I changed my plans, it was a waste of time. But it wasn't for what I wanted to do at the time. My brother is a radiographer which required him to have a degree. Doctors, vets and lawyers all need degrees, so no, degrees are not a waste of time if you need them for a certain career path.
