Thatcher did something similar in the 1980s when she allowed people to buy public housing at rock bottom rates. Those houses returned to the public stock before then when the occupants moved or passed. Now they were gone permanently causing the housing crisis which means lack of rentable properties push those available skyward to no longer be affordable by 95% of the population.

Thatcher and the tories are the worst things to have been inflicted on the English people for the last 40 years.
