It’s hard to convincingly look like a man of the people while you’re busy impoverishing the public
It is tradition that politicians’ relatability is measured by knowing the price of a pint of milk. Which, I’m guessing, will be circa £9.80 in a couple of weeks’ time. Margaret Thatcher was very proud of being able to answer this question, an aptitude somewhat undermined by her nicking it all later.
The problem with having recent governments packed with millionaires (at one point it was two-thirds of the cabinet) is that, even if they could answer this question with certainty, it wouldn’t detract from the fact they have zero idea what budgeting and financial constraints are like for most of the public.
