This is a fun discussion
Lots of us i reckon don't know the price of certain things-so I'm assuming many of us are working class and yet we out of touch
Now whoever the PM is I am not worried that he is out of touch with prices as he lives in a far different world to the rest of us (as do footballers,royalty,golfers etc)
I would assume he does not go down to Tesco on a regular basis (why would he) He is paid to run the country and that's what we want him to do.
Whether you belong to Tory party,lib dem,Labour,monster raving loony party and were in power you have to get on with your job thats what we pay you for
