Commenting on The Push National Student Debt Survey 2010, Universities and Science Minister David Willetts said:

"A university degree is a very good investment in your future and it must be right that those who benefit contribute to the cost of their education. Graduates on average have better employment prospects and can expect to earn at least £100,000, net of tax, more than non-graduates across their working lives.

"Graduates do not start paying back their student loans until they are in paid work and earning more than £15,000. We are committed to increasing social mobility and widening participation in higher education. Any changes to student finance will take into account the impact on student debt and the need to improve the quality of the university experience."
