What is the alternative?
Apprenticeship ideal but few and far between.
While a graduate and non graduate may start off on similar salary, no degree likely means very limited career progression.
Getting that first job can be difficult, but once graduate has some work experience, in many jobs they will usually be selected over non graduates.
Keeping loan amounts to a minimum is definitely advisable. Help from Mom and Dad where possible, part time jobs, summer jobs, accommodation choices, etc. Local uni where they stay at home & commute saves an absolute fortune. Study abroad can also be an option for cheaper college education.
In the US many parents start saving for college costs when their children are born. Maybe that is the way forward? Little and often for duration of 18 years. Not easy during COL crisis I know. £50 a month over 18 years is almost £11k before factoring in interest.
I would always encourage 3rd level education so long the academic ability is there. Ideally a degree that will result in a job! But I am also a big believer in following your passion and trying to make a go of it.
