Handing a group of people this incompetent a bigger role in our lives is bananas.
But currently no-one is bothering to make things better, which is why they are getting worse.
They may not manage it perfectly, but that’s less important than the fact that someone wants to manage it. See, if you just leave things alone as Tories like to do, then the rich and powerful abuse the poor and downtrodden. This has always happened. Labour want to prevent that from happening. So they might not get it perfectly right, but at least they are trying to fix things by taking an active role. The Tories won’t, because it is literally the entire point of the Tory party not to bother.
If there were two parties both promising to fix things for the worse off, then yes you would be right to compare them. But Tories are not going to fix things for the worse off – they are just going to ignore them and wash their hands, cos that’s what they do. Small state.
In fact, the Tories one attempt to change the system that helps people – Universal Credit – is an unmitigated disaster in terms of execution, never mind the fact it is designed to allow benefits to be cut more.
