First off, you are correct, this topic does belong in the Politics section and I suspect it will land there :)
I think all of this is related to Brexit. I watched a 30m video put out by Financial Times. youtube. com/watch?v=wO2lWmgEK1Y FT is not a left leaning, welfare state loving publication. They put out this video which explained what has happened to the economy since Brexit and the impacts it has had.
The UK when it was in the EU was part of the 3rd largest GDP. That got them a HUGE market to sell to. Now because of Brexit, They are ~ 1/8th the size. They lost all the benefits of trade within the market.
Just imagine if the US had 1 state that was NOT in the US and what would happen to that 1 state in trade? It would make that 1 state, in essence, it's own nation and now what? That is what Brexit did to the UK.
