If a person is in debt they are not free.
If a person is in debt, they do not have the money to pay the debt. They are obliged to either work to earn the money to pay the debt, or to suffer the legal (state-enforced) consequences of defaulting.
This is state backed slavery.
That the government is enslaving English graduates by pushing them to take loans to pay for their education is obscene.
If the government are so sure about the value of degrees (which are obviously worthless if everyone has one - someone has to clean the toilets) - then the government should be confident that they can recover the costs from later earnings by those graduates, and should keep degree courses free - or even sponsored with grants (for those from whom it is likely that they will recover the costs later in taxes).
