A moment ago, Andy, you were arguing that private sector education didn't confer advantage; that people simply sent their children to private schools because they were out of the country or suchlike. Now you seem to be arguing that abolishing private education will 'bring people down to a lower level'. I fear you are making it abundantly apparent that your private education did nothing for your logic!
Or yours, Martin!! I simply said that while you espouse a system that claims to drag the educationally weaker up by association with the stronger, it doesn't actually work out that way in reality; if anything it drags the stronger down to the average and the weaker are largely untouched, except to see what they are falling short of.
