You DO realise that while benefits have been cut, in order to get employers to raise their wage to one that people can actually LIVE OFF, people will have LESS money coming into their household than they can ACTUALLY LIVE OFF. The change won't happen instantly.
So what happens to all these people who are meant to go out and take jobs that don't pay them enough to live off?
They starve or don't pay their rent, so that they DON'T starve...
The wages need to rise to a liveable amount FIRST, or we are setting the poor up for starvation and homelessness.
EITHER the Government can't see this, or they choose to ignore it even though they can see it.
And I know which is true. As it is spelt out in the Universal Credit Policy Briefing Notes in the passage that states that "Due to a reduction in their income after the changeover to Universal Credit, some families will become collateral damage"
So IMO, the Government KNOW what the outcome of cutting the welfare system now WITHOUT sorting out the reasons WHY it is the way it is first, they KNOW that it will cause homelessness and starvation on an as yet unimaginable and unprecedented in modern memory level but they just don't give a shit.
The money IS there, the legislations HAVE been proposed that could cut the Welfare budget by the same amount without causing this level of deprivation, but they just won't act that way.
Putting in Rent Controls would slash the Housing Benefit budget. If LL's that were overstretched lost their 'extra' home, they would still have somewhere to live, but it would flood the house sales market with extra houses for people to buy. As there would then be much more availability, house prices would drop, more people would be able to afford to buy, thus slashing the Housing Benefit bill even further. And it also has the added effect of more money circulating through the UK's economy.
It'd hurt people left in negative equity too, but it's short term pain for long term collective gain (after all, we're all in this together, so Call-Me-Dave tells us). It would lower the overall Welfare bill, which would put less pressure on the taxes paid.
The other thing that would drastically lower the Welfare bill would be to raise the NMW to a liveable level. Which is roughly £10/hr. As Garlic says upthread, Tesco et al are hardly likely to stop trading in the UK and lose one of their main income streams just because they are made to pay their staff a living wage, are they - it wouldn't be the best thing for their shareholders, would it?
This would cut the Housing Benefit bill as those in NMW work would no longer NEED an income top-up in order to pay for a roof over their head. It would ALSO cut the Tax Credits bill as why would you need an income top-up if your wages are enough to live off?!
It's never going to happen though, whilst those in charge of the country are protecting their own interests (MP's with property portfolios voting against / dismissing rent controls) over and above the interests of the average person.
