I think the focus is back to front and "wealthy" needs a more scientific definition. Too often anybody above fsm is deemed wealthy which is ludicrous. In the same breath as "wealthy" "able to afford private" often follows. Very few can. Surely as regards benefits to children part of financial wealth is disposable cash. Those without the bank of mum and dad, not lucky enough to buy a long time ago,without social housing,zero top ups,debts......often have just as little and sometimes less.
Surely everybody who isn't wealthy has the right to social mobility,not just a minute ever shrinking few on fsm. So what is wealthy? Fsm is just a tiny band grabbed on by politicians to keep everybody quiet whilst they say"we've done our bit".What we have at the moment is a sandwich system. The group in the middle is huge.
And yy to the posters last point. Those on fsm aren't often in the top sets at comps,the very group who could or should access grammar schools. The excuse given by those against grammar schools is that many just aren't suitable,have Sens etc which is fine but that argument needs to go both ways in both sectors.
