We import a great deal of our stuff, including much of our food.
Some years back, we voted to devalue our currency. Some people even said it was a good thing. Clue - it wasn't! What surprises me, in truth, is not that prices have gone up, but how relatively little they have gone up taking all factors into consideration. Obviously, we have to factor Ukraine and Covid into the picture.
We are poorer than we were, that's just a fact. It's showing itself in low income increases (for most) and high inflation. Mind you, some at the top end are undoubtedly taking the piss. (But if you moan about that, you're 'envious' or a 'Commie'.)
Get used to it. If you're lucky it won't get substantially worse. But I see nothing in the economic barometer to make me think it is getting substantially better any time soon. The contrary, if anything.
My advice? Be born to rich parents or develop a rare skill not easily replaced by AI.
