UK Background: Last government (the coalition) decided to move
part of the financial burden of a University education from the state (in the form of a 'teaching grant' paid directly to the University) to the student (in the form of a low rate loan as described by SixSigma). This was entirely within the ideological position of one of the coalition partners, but was a bit of a u-turn for the other partner with rather drastic results in terms of support.
The Student Loan Company in the UK has to borrow money at commercial interest rates in the financial markets. The difference in costs between the interest rates paid by the company and the interest paid back by the students will be met by the government. It isn't clear to me if there will actually be any net saving to the taxpayer at all - I recollect seeing (but can't find a reference at present) an analysis that suggested that the policy will actually cost more money compared with the previous direct grant system for the next 20 years or so. I suspect the payback period will depend on the number of graduates who get stuck in low paying jobs.
I would love to see any more recent analysis.
Back on topic: good luck to these people!
