Why are we so insistent that people buy their own houses? At a time when a flexible workforce is needed it impedes mobility of labour.
In Germany, house purchase is characteristically only done at a fairly late time in people's working lives.
From the government's point of view, making people buy their own home means that the taxpayer is no longer either being or paying for a landlord with responsibility for the upkeep.
Cameron's definition of 'affordable housing' (upwards of £400K in London, if I read it correctly) is nonsense to start with. Ultimately, it still won't fix the issue, which is that there are just not enough houses being built - it doesn't suit the builders to flood the market, scarcity drives up their selling price without affecting their costs.
The government needs to increase the number of houses being built, not the proportions of the too small number that are alloted (badly) to particular target groups.
