I don't agree that those who go later should pay less.
But I also strongly dislike the pressure that young people feel, to go to university straight after their A-levels.
People feel pressurised into going straight into uni, even if they aren't entirely sure the course is right for them. If you take some time out and really give it some consideration, I feel you are more likely to make the right choice for you. Too many people choose courses that in hindsight they wouldn't have. And I blame that on the panic they feel into applying straight away, before they've had time to actually think about their career choice.
Young people also feel pressured into applying through clearing and studying at a university or course that they wouldn't have chosen themselves, or they won't end up happy in, because they feel the immense pressure to go to uni straight away. Whereas if they took a year out, they'd have time to rethink their options, properly look into the universities and apply to ones they're genuinely interested in.
I think partly that is down to pushy families/ schools and their expectations, and partly down to not wanting to miss out, a kind of conformist pressure to want to go to uni the same time your schoolmates go.
In the long term, that year and a bit out will make no difference. What does make a difference however, is rushing into choosing an entire degree that is not right for you. Choosing to spend three years in a location which is not suited to you. That can have a much more detrimental effect on your life than taking some time out before uni.
