Firstly: student debt isn't like normal debt, it doesn't work against you, you can't default on it, payments are very small. There's a very interesting Martin Lewis article that says we need to stop calling it debt and call it whatever they do in NZ or Aus (can't remember exactly!) it's an investment. I'm talking for the UK obviously.
Secondly: the sentiment "I feel one of us should have a degree" is flawed and is very much reflected by the society of that we live in unfortunately, not everyone should get a degree, not every job needs a degree, universities are businesses and while I said above it isn't like normal debt it's still a lot of money to do something you don't need to do.
Getting a degree because it's more socially accepted is silly (but I understand xx) when I left uni the people who didn't go were earning more than me as they had been working longer! I had to go to uni, I wanted to be a teacher, I didnt go down that route in the end but I still use my history degree and am now doing a masters, not because it looks good but because I have to to get to the next level, lord I wouldn't be doing it and paying for it if it wasn't necessary!!
We need to move away from this belief university is a tick in the box in life, it's not, the truth is degrees are becoming meaningless now because so many people have them and then so many people go into jobs that don't even require them, I have friends who omit them from their cv- imagine that, £20,000 spent and 3 years hard work to wipe it from history?! (I say £20,000 that's because we're on the old scheme, it's obviously more now!)
I totally get why 18 year olds sign up to uni to do a degree despite not knowing what they want to do, it gives you more time, it can be fun, and potentially it can open up job prospects. But it's not really a good reason to go unless you have an occupation in mind, not a chance would I have gone to university if the jobs I was striving for didn't require one. Going from your previous threads you really sound like you're at a cross roads right now, but in all honesty given what you want to do I think you will do better to spend your time and money on getting experience, not a degree.
