I knew a working parent in shared accommodation; zero hours contracts meant keeping anything else together on a stable basis was impossible.
The other tenants weren't around for long and some were a concern and now she doesn't have custody any more. In fact the child isn't in the UK as her ex is abroad and she hasn't seen him for over a year as he can't leave that country due to immigration rules whilst status is processed.
Poor woman, she chose to give up son as she felt he deserved more stability and I think that was brave of her but almost killed her.
The thing is, over crowded housing and instability are linked to low educational outcomes, poor health and unemployability: things that cost the UK a lot financially. Poor housing (bottom end of private sector) is the same, of course.
I don't support the tax, I think people should be required to move into smaller where it is available and if they refuse then a subsidy is OK, but there should be more exclusions (disabled adults needing a separate room for storage of equipment or who can't sleep together being a significant one). I also think that pensioners shouldn't be exempt- and this would affect me as my parents are in council housing albeit still working at seventy- many can afford the top ups and if decent accommodation (local to area) is available hen it makes sense. I know my parents wouldn't move as they provide essential childcare for all of us but I think we sisters could chip in to cover that extra cost when they stop work, seems only fair (they don't have pensions because their scheme collapsed just as they hit retirement age, not from lack of putting aside- lots hundreds of thousand and the plan to leave council housing and purchase a bungalow was ruined).
Greengrow you really should attempt at least to display some empathy for those less well off. It does wonders for a person. We are not subject to the tax (neither in council, nor without work) but I can see so many flaws in it.
