Since the living out allowance has not been available for renting for several years, the only way anyone could have been ‘doing well for themselves’ would be if they had rented years ago under old terms and thus taken the hit with inflation and VAT, and also been able to convince their landlord to reduce their rent by your quoted 30%. The ones who purchased which is the only way to move out now not so well, and not to mention the vast majority who neither rent nor purchase.
Thus the numbers who did ‘well for themselves’ are vanishingly small.
How you can dress up a decrease in pay and terms as a good thing I don’t know, unless you live high up in the thin air of the bouncy castle that is, or your just a troll.
