most students never repaid the full amount
That is, of course, based on forecasts, as no one has yet reached the 30 year cut off point for the scheme that's just changed and was only in operation for the last decade or so.
It's also VERY misleading, as it's based on paying off ALL the loan, including the accumulated interest. The interest can easily end up being more than the amount borrowed, so whilst they may not have paid off the their loan, many will have paid more than the amount they borrowed and have been eating away slowly at the interest, rather than the capital, for the latter part of the forecast 30 years.
You don't have to be an ultra high earner to end up paying off huge amounts of interest either. When we did spreadsheets with DS for his tuition fee element of the loan, I seem to remember the earnings level to be as low as £50k or so to pay off the capital, doubled up with interest within the 30 year period. So basically borrowing £27k and paying back just short of £50k over the 30 years! Ouch!
The "forecast" of not paying much back only really applies at levels of average earnings of less as they'll not even pay back the capital, so the loan repayments remain pretty insignificant. Likewise, the ultra high earners pay it off much quicker so don't incur anywhere near as much interest. As always it's the "middle" who are squeezed, i.e. those earning in, say, the £40k-£60k range who DO pay it off more or less, but incur huge interest in the meantime.
