The poor already get the shaft in the UK, the changes coming in today just exacerbate the shafting.
The 'scroungers' narrative is firmly established. Anybody who is unemployed, disabled, homeless or otherwise vulnerable is made out to be a pariah. Despite the facts, the 0.9% of actual benefit fraud, the 3% of people who fail the disability tests, the 40 applicants for every available job, if you're not in work, you're a scrounger.
You can see it in this very thread. The rank animosity from the 'haves' to the 'have nots'. "They should be poor", "They're lazy", "They all have Sky and smoke and drink", etc. It's a shameful reflection of the garbage dredged up by our sensationalist right-wing press, an extrapolation from anecdote to data that doesn't match reality.
If you are subsisting solely on welfare, you are probably leading a miserable and destitute existence, and it's about to get worse.
If you are so firmly attached to the 'unemployed as scroungers' bullshit, remember that the majority of the changes negatively impact the working poor. The people that you no doubt feel are 'doing the right thing', the people that 'got on their bike', that 'pulled themselves up by their bootstraps'. They're getting fucked over harder than almost anyone else.
The post war consensus, shattered under Thatcher, has finally been killed off. The class war isn't over, but the rich fuckers are winning.
