"1. Bedroom tax Not paying benefits for empty rooms."
Lots of them aren't empty... they have children in them, children that don't count as needing their own room because they're under 10, or 2 - so they're supposed to move until their children reach that age.
Except there's no smaller housing stock to move to.
They can of course move out of the area, but that means giving up their jobs, school places, losing childcare from friends and family.
Pensioners however, they can have as many empty rooms as they want, for free.
"2. Denying disability benefit to 165,000 people Stopping welfare to those that dont need it."
The appeal system isn't supposed to be what grants benefits, firstly it means people with disabilities having no income until they win at appeal, secondly the appeal costs the government extra money - it's supposed to be a back up for the odd case.
"3. Scrapping housing benefit for 18-21 year olds Live with your parents or pay your own rent."
And if you can't do either?
