"You may be right but I will say that it is widely believed that A level standards have gone down."
They clearly have. That's why I know profs who didn't get straight As at A Level: it just was so rare, that if you made that a criterion there wouldn't be many profs aged over 40.
"By creating a market where richer kids are able to access the most expensive education more easily I am convinced standards will come down not up. "
So start failing some people. One, er, "surprising" fact is that with larger intakes, the percentage of people getting firsts has risen, as has the percentage of people getting 1sts and 2:1s, and the rate of people being thrown out has if anything dropped. Odd, that.
"If you're bright but not wealthy the difference in fees of say £3k at Uni down the road v. £7k at RG will feel significant and less affluent families will be less able to read the subtleties of each university"
But that's happening now. You and I know the universities that are good, and probably (in our own fields and related ones) the departments that are good. And we know people who can tell us that for most other subjects. If my daughter wanted to do subject X, I'd have her talking to a senior figure from a good department, via middle class net, to scope out her options. People without regular access to HE don't have that, which is why they end up doing crap courses at weak institutions and paying the same for it as tey would to do a good course at a good place that they could have got into.
Why? Because 14 year olds aren't stopped from doing bad GCSEs, and again at 16. You and I know that if you want to keep your options open, English, History and French is acceptable for almost all humanities courses and Maths, Physics and Chemistry for almost all science and engineering courses. There are exceptions, and if you're certain what you want to do, go for it, but those traditional groupings are the safest options. The more people pay for their child's education, the more likely that they are doing one of those sets of A Levels, based on the appropriate GCSEs.
Now, over in Bash Street, how many people have those A Levels? Fees be blowed: with A Levels that they're doing, no where high up the league tables will look at them.
