A huge part of Labour's promise this GE is to scrap UC - & other benefit iniquities such as the bedroom tax (which also pushes people into poverty).
And replace it with what?
It's all very wonderful to make grand pronouncements but what comes next?
There's nothing wrong with UC as a system - it's pretty good actually
However, it does need to be paused & the anomalies & inherent problems properly addressed
Bedroom tax? No different to military housing since it began - if you're living above entitlement you pay the difference.
However, the failing with the 'bedroom tax' (not a tax) is that people are paying for the above entitlement difference when it is not their choice to live above entitlement - in the military if there is no accommodation which fits your entitlement & you go above then you only pay the rate you should have (ie lesser)
(Further, If you are in above entitlement because none available at the proper size then you shouldn't have to move when one becomes available - you retain your right to stay at lesser rate)
As with UC, there are problems, yes, but overall there is nothing inherently 'cruel' about it
