Yep all these anecdotal stories are pointless. However the data does show those with degrees earn more over the long term than those without. Obviously in that there is going to be the ones who never went to school but are now multimillionaires and those who have a degree masters PhD etc and are now sleeping rough.
I’m going to guess your friend who takes photos and travels all over was not helped in those pursuits but having a degree in history.
Of course he wasn't, also the other one did a PGCE after Uni.
I also can't talk either.. as I did an environmental management degree. I've spent the last 10 years doing anything but that.
However having got past "foot in the door" level it is very handy to have been to university as with it being a science degree a lot of time was spent collecting data, analysing the results and then writing it up which I have to do as job quite regularly. Also I've had to design and deliver large scale training across a national company in a month. At that point I was very glad to have experience slapping power points together and delivering them to a large audience.
So while sitting studying environmental law, spending hours in twin span poring over dendograms etc in my case was a waste of time the process of working has been the useful bit. It's also worth noting if I want to move up a degree is required as well as the requisite experience so if I had not done a degree I'd not advance past where I am now, also where I am now required a minimum of A levels.
So I'm sure there are thousands of people in the same situation as me where they aren't doing what they thought they would be but the degree is still serving them well hence the increased earnings potential.
I'd imagine that doesn’t apply if you did an aromatherapy degree though.
