I’ve been there and done that friend. Whilst you may be brilliant at managing your finances, and I applaud you for that, countless other people aren’t. And I would say students today are the same as students have always been, they just have a smartphone these days.
I found myself at 18 years old having what was essentially free money thrown at me through overdrafts and credit cards which, coupled with a sudden desire to prove my independence and enjoy my first time freedom and it meant I snapped every single opportunity up and to hell with the consequences, I could sleep when I was dead after all.
That overdraft was soon maxed out though, and I had no hope of repaying it at uni. Nor did I have any chance of repaying it when my account suddenly changed to a graduate account and I was told I had to. It took years to understand and recover from my student debt.
What banks do to students is immoral. They train you to take, in the first years you can get credit, as much credit as possible consequence free. Perhaps you might get a free Kettle or a Railcard as well. But then they stick you with payments as soon as you are spat out of the university system and realise you are suddenly saddled with more debt than is manageable or reduce the overdraft in stages, as if you Suddenly have all this spare income.
Suddenly the expectation is, having spent all of your adult life to date being able to spend money without issue, that you have an income which allows repayment and you are savvy enough to be able to manage it.
Some are - you are. Lots and lots aren’t and what a profit banks make from them.
TL;DR - Be careful out there. It’s easy now but it ain’t later on
