In effect, more successful English graduates subsidise everybody else (because it is supposed to be revenue neutral). And specifically English, because only English students pay the full £9,250 per year. (Scottish students pay nothing, Welsh and Northern Irish a reduced amount).
The English subsidise the "United" Kingdom but are discriminated against when it comes to social provision paid out of general taxation. Unlike Scotland, Wales and Northern Ireland we do not have a Parliament for England looking after England's interests. Instead we are ruled by the Union Parliament which includes MPs from Scotland, Wales and Northern Ireland whose remit and interest is their own respective nations, not England, but who get to vote on legislation that affects England without England having the equivalent ability to interfere in the Scottish, Welsh and Northern Irish Parliaments.
It's more complex than that; Scottish students are liable for the full tuition amount if they study in England, and the repayment terms are different (9% over £18330 currently, but it is changing), but Scottish students studying in Scotland have tuition paid for out of the Scottish government's general funds (and you can argue whether the majority of the government's income through Barnett Formula is fair or not to those elsewhere in the UK), though are still eligible to get bursaries/loans for living expenses.
And as a resident of London, my tax will be counted as English by the books, reinforcing the idea that England subsidises Scotland. But really it was the Scottish government's progressive tuition fee policy which enabled me to go to university in the first place.
If you really want to break the UK down and pit us against eachother, then why not be honest and say that London is subsidising everyone, including the rest of England? The English aren't discriminated against, they just choose to vote for politicians who are against devolution for England, for tuition fees, and against social provision paid out of general taxation. Things would be worse without the MPs from Scotland and Wales.
As for London, it is the capital of England just like Edinburgh is the capital of Scotland. Both are richer than elsewhere in their respective countries. I am not sure what point you are trying to make.
As for the Scottish Government's "progressive tuition fee policy", it was voted in by Scottish MSPs. The tuition fees paid by the English were forced on the English by MPs from Scotland who knew their own constituents would be unaffected - MPs from England (and Wales) voted against these fees but were overridden by Scottish MPs. That is not the fault of those MPs that the English voted for, but rather by a system of Devolution designed by effectively the Scottish Labour Party. And every time anybody who is English tries to address the issue there are howls of outrage from the rest of the UK, and Scotland in particular.
But what lists? There are so many, Universities choose to showcase the convenient ones of course.
Repayment starts at £21,000pa; so if you earn £30,000 you'd pay back £37 per month
