One thing that Trump has taught the world is that you cannot ignore the markets in a capitalist system. Liz Truss taught the UK that when she was (briefly) in power. We have seen what happens in nations like Venezuela (though many will blame western sanctions for that).
This is important as Labour have limited room for movement when it comes to the economy. The Conservatives ruined it and as shown in the deputy leader’s debate last year, knew that Labour would have to raise their nickel or make cuts to spending.
There have been calls for Labour to increase debt and spend, but the people calling for this forget the damage this caused when Truss wanted to increase the amount the nation owes.
