I certainly agree degree costs for locals are far too high, but that's a different issue to international students, who are paying more than twice as much as the locals for a degree.
I have paid my way through both undergraduate and masters degrees, as well as some vocational courses, while working fulltime, so I do know what you mean.
Incidentally, if local students can prove their degrees/courses are work-related, they may be able to claim some costs back at tax time, although not the actual course fees.
This can include travel and accommodation for study, a new laptop every three years, home office costs, purchase of books and software etc.
A good tax agent should be able to advise.
