Paying the rent directly to landlords, no questions. I would set the minimum benefits rates below the minimum wage so work always paid more, but if someone was working I would top them up to their equivalent full time wage if they worked more than 20 hours a week.
People with disability, this won't be popular, but I would with the huge changes in home working have more of them working remotely! UC was supposed to bring benefits in together, and I think as a concept is actually a good idea, but as with any benefit reform everyone jumps on it and doesn't really give it a chance to bed down.
Alongside all of that though, I would invest in the care, education and development of those claiming benefits to support them to get employed and improve their lot, but claiming benefits should not be more lucrative than working unless a person is totally unable to work. Assessing that is not easy though, and will always be seen as harsh by people who feel they have been hard done by when the result comes in.
As somebody else said why to those of a Conservative bent think you can beat people out of being poor.
There's obviously a need to deal with those, whoever they are, that are perfectly capable of work but choose to live on benefits. But they're a very small cohort; you cannot deal with that by manipulating benefit rates down. There's already a cap the purported reason for which is to ensure people are no better off on benefits. It doesn't do that; the reality is that it penalises those who rent privately. The way to get people back into work is by increasing opportunity. While £15/hr is aspirational the current National Living Wage is set way too low. Here, in Northampton, a single person working 36 hours at NLW and renting a one bed flat privately, even if they could get a place at the ceiling of what is payable (most pay more) would get £120/month in UC.
It's simply inhumane to penalise somebody with very real health issues, including receiving/recovering from chemo by deliberately setting rates below the minimum for a reasonable lifestyle.
One of the problems with reform is that all the tweaks down the years have been aimed at reducing what is payable. That includes the Osborne era freeze, the cap, the two child limit, rent caps set at the 30th centile, taper rates, work allowances limited to certain groups, removal of extra money from those who's health problems are not utterly life limiting (nothing extra while you're on Chemo for example) and the 13 week wait for any extra money for health unless you're terminal.
I'm sure working remotely might help some people who cannot hack the shop floor, the office or the journey in but the idea that it's a game changer for those with ill health or disability is nonsense on stilts.
And please don't try Whataboutery regarding Labour governments and Mental Health. It's been a Cinderella area for as long as my career has touched on it (at least the nineties). The Tories have been in power for 11 years; ample opportunity for a step change. At least things stopped going back under Labour.
