I'm sure you're not naive enough to think ministers and their aides don't take advice from business owners, but let's look at a few high profile candidates that would fit your bill:
James Dyson who advocated Brexit and then took his company to Singapore?
Tim Martin of Wetherspoons who advocated Brexit and is now endlessly moaning he's lost loads of foreign staff?
Rees-Mogg who advocated Brexit and then moved the fund he manages to Dublin?
Tice who advocated Brexit and hates immigration who has now partly moved to Dubai, a city built on slave immigrant labour and a bit of Sharia law thrown in for good measure?
Jim Ratcliffe ,need I say more?
All canvassed for Brexit and therefore the likes of you and me to be worse off and then fucked off out of here. And you actually want the likes of that lot in charge?
I'm sure there must be some decent ones around, oh, actually the owner of Timpsons and Iceland come to mind as I type. Any more and I'm struggling.
