@TapasForTwo In my home country, university students are fully supported by parents throughout. There is no expectation that students will fund anything until they graduate. There are no jobs for students anyways. it is a third world country so you might not want to take that as the "model" to follow.
Personally i think if parents can afford it of course they should support their offspring through their studies, but if they cannot, it shouldn't just be, "You are 18 now, we wash our hands of you!" type thing thing, it should be a sit down conversation about how they can meet the short fall, if there are some hrs the young person can do for work, perhaps parents or student can get a loan. Education should be seen as an investment in the future.
On another topic and probably controversial but I don't think 18yr olds should be classified as "adults". I think 18-21 yr olds are on the 'cusp' of adulthood. The category eg "Adolescent" to mean someone who is no longer a child but still needs advice and support from parents should be the official label and should be the official term for university students or anyone of that age.
To me an adult is someone who is at least 21yrs, no longer requires input from parents (barring the occasional help, eg childcare, a loan etc). They can pay for their own accommodation, they have completed their education or training and can get a job.
The confusion in the UK is by calling 18yr olds "adults" people think, "well you're an adult!", therefore you should pay find/fund your own way. But Universities (in this case) are saying, "there's a parental contribution expected". it contradicts the meaning of the word. The reality is most 18-21yrs olds aren't equipped enough yet financially or mentally do this on their own.
