Are you special needs ? Who goes to University to limit them selfs to earning 21k.
You need to visit speakers corner section and really read into this properly to understand the real implications of this bill passed.
Typical scenario
That pakistani fella in the video, his dad probably is some mini cab driver, get **** wages, cant afford to pay for his son's travel, accommodation, food and books.
That grant that you mention , will probably just about cover his expenses and material needed to study.
Students from poor backgrounds used to take that £2700 grant, top it up with University Busary or part time work and pay off their SLC loan.
The free grant wasn't meant to be used in that way, but a lot of poor kids were using that method to pay their fees.
Another point, not all professions have high earning potentials.
for example teaching, average salary 21-24k and they reducing grant funding by 80%.
So how the hell is a NQT going to afford to budget and pay their debt with a 20-30k debt hanging over them.
