No-one is choosing to have kids to get benefits. No-one is choosing to suffer on UC. They're just not. I know this because I know you can't live on UC. Few can survive on it, much less live on it. And if you do genuinely believe that people are opting to have babies instead of enter the workforce then you need to look at the reasons why not blame the people because UC (and to a lesser extent the legacy benefits) is a miserable, unstable existence. Even before UC people on unemployment benefits were far from comfortable. If people really are choosing to stay on the pittance offered on UC then something in society has gone very, very badly wrong.
And, putting the mythical benefits babies aside, the vast, vast majority of welfare benefits are claimed by working people. I work. I work 13 days a fortnight for two different companies and I still need benefits in order to pay essential living costs.
One of the companies I work for is a global fortune 500 company. Explain to me how it is a) fair and b) my fault that a global fortune 500 company gets to have its wage bill subsidised by the UK government? Explain to me why they are not forced to pay their staff a reasonable , living wage. While you're working that out, you could also have a think about how they managed to be shortlisted in the UK's top 50 companies to work for when they can't even manage to pay their staff without government assistance.
My weekend job is in an essential health care role. Please explain what you think would happen if all care workers (because even those working 40+ hours a week need benefits to live if they have a family) trained up and left care in order to not need benefits anymore.
Society is fucked. The people at the lower end cannot get out of poverty no matter how hard they work because those at the top are hoarding all of the money.
