Good, they should be able to socialise, but ime, most don't seem to have loads of cash to be out a lot. Some are struggling to afford food without going out. Making out like most student are rolling in cash is a joke and sounds like someone who is talking nonsense.
The fact is that if a student only get the minimum maintenance loan and parents thought like you, that kids should sort their financial situation out, then they're down thousands of pounds just by paying their rent. Lots of courses really don't allow for students to work that much to make up the short fall, not if they're going to keep up with their studies anyway.
A lot of jobs require a degree, if not straight away, then later for any real career progression.
If parents have the money, and their child chooses university, I do think those parents that don't help are shit. I almost didn't go years ago due to it. Thankfully a lovely teacher helped me through the process but it was hard. I had very little free time of spare money as I was working so much.
Your views don't seem based on the reality of being a student right now.
