It is insanely easy to end up homeless, the vast majority of the working class could last a month, maybe two if they've got some savings.
What's noticeable here is the £2,000 given is quite a big lump sum, actually capable of helping people make a difference. It'd be inhumane to test it, but if that £2,000 was split up into 12 payments of £166, would it have made as much of a difference? I doubt it. Yet that's how most benefits work, a pittance a month. Just enough to keep you alive, nowhere near enough to actually help lift people out of poverty.
