You cannot distinguish between Johnson the man and Johnson the PM? I don't care who he is, only what he does! That's a handy throwaway meaningless phrase, what he does will flow directly from what he is, so what he is matters.
Interesting you automatically assume a mention of inherited wealth should entail bitterness, actually I'm lying, it's not interesting at all. It is the entrenched power and privilege that comes from inherited wealth that is the problem.
As for what Johnson will do for the economy, I doubt he'll be around long enough for us to find out.
