My friend at work raised the bedroom tax with me a few weeks back. Her neighbour was moved from cramp conditions into a 3 bed council house with her two children. Under the new 'bedroom tax' she is being forced to move back to a two bedroom home and her kids made to share. She is rightly very unhappy.
I completely endorse the concept that scarce resources should be distributed fairly including bedrooms in social housing, but this new scheme goes too far and is being handled very badly. It may be fine for kids to share a room under some circumstances but most of the time they need their own space. Forcing families to move out of their communities into crampt condition is plainly wrong.
But it's all OK if they take in a lodger...
