With these Tory MPs, I think many are utterly bewildered that the public are demanding any help from them. In their minds this economic issue a) isn't as bad as is being made out and b) doesn't affect them in any meaningful way.
To their minds, the Tory government has consisted of: 2010-2016, fixing "Labour's mess"; 2016-2020 getting Brexit done; 2020 getting the "big calls" on Covid right. We, the public, should be grateful to have had them in charge this whole time.
Now, when their constituents are showing up saying they now cannot afford to eat or heat their homes, they have no answer at all and so reach for any old nonsense that comes to mind. You can eat a meal for 30p. Get a better job. Take on more hours. Use own brand goods. Wear a jumper.
They do not get that voters are looking to the government to help them, and with no help coming they will possibly not win the next election. And these Tory MPs have got to be the least intelligent bunch I have ever come across.
