If a person buys they reduce the supply. But if they could afford to buy, they could buy a new build or commission their own property to be built and increase supply.
Buy to let is immoral because it bids up prices of existing property, it needs to be replace by build to let, profits then fall as demand is met, capital invested correctly and everybody happy.
The current system is insane and prices the likes of me out of work.
Cheers for paying my dole and housing benefit, just bare in mind my housing benefit is a subsidy to you in your cushy housing job, by rights you should be on the dole and I should be able to work in the capitalist economy. Thank the lord for the black market and clandestine production, for it is production where real wealth lies.
