That's not how economies work, the figures show it be be true whether you 'feel it' or not! 🤦♀️ The last few years have been dreadful for all economies worldwide, not just the UK. There are many reasons but covid is of course one of them. We are still in recovery but hopefully on course for a soft landing, and we are outperforming almost everyone else. You may never 'feel it' though as we could have the best economy in the world and you'd still be in poverty if the money isn't distributed towards you. Look at America - they do have the best economy, and they have extreme deprivation.
It's also not being used to sneer at Labour as it has nothing to do with Labour, other than they are apparently trying to convince people that the situation is much worse than it is. I'm just trying to fathom why they haven't mentioned it, especially when they were so quick to claim that they'd unearthed a multi-billion 'blackhole' that the Tories had apparently left them. You'd think they'd be thrilled to learn the economic outlook isn't anything like so bad as they believed. Now, they may just be so used to being rude about the Tories they just can't bring themselves to say something nice about them... they may be intending to take credit for the growth when it continues and hope nobody remembers it was already growing when they took over... or they may be concerned their policies are going to inhibit growth in which case they can then try to blame the failing economy on the Tories, again hoping nobody realises how good it was when they inherited it. All these possibilities are a bit worrying - if they have genuine confidence in their ability to stimulate growth they should be happy to acknowledge that we're already in a very good place and set to continue improving even if we do nothing, and then when they beat all the already positive forecasts they can show unequivocally that is was their policies that did it, engendering trust in both Labour and in left-wing economics.
