The CH propaganda machine says to ignore past criticisms of the school (bullying, sex abuse by masters, etc). OK. But a lot more is known about the effect of boarding these days and there is no modern theory of child development that recommends sending a young child away from home to be brought up by complete strangers. No other western European nation does it except as a last resort (peripatetic parents for instance). Look at the results. Boris Johnson, Jacob-Rees Mogg, David Cameron, George Osborne - and of course not forgetting Steve Hilton.
