Free Trade makes everyone richer except protectionists. See the Corn Laws and Imperial Preference (ie the last 2 times the 'Tory' party split) for more details. Remainiacs (excluding idealistic students) have no problem seeing wages fall for the low and no skilled so long as their house price keeps increasing.
The corn laws where extreme, A ton of imported wheat would have needed to cost over 1300$ in today's currency , 6 times what it costs right now (~220$). That's not protectionism, that's outright mercantilism (which practically forbids any imports with absolutely excessive tariffs)
US are your baby? The baby has outgrown you decades ago and is now ordering you around like their little pet. And ROFL on the rest of the text there. You really think tiny little England won't get squashed by the US in their demands? Trumps US is all take and no give, what part of America first or their "trade offer" (which is basically just asking to do everything for them and getting nothing in return) do you not understand?
I do agree with May on the national Security to some degree. It would cut off the UK from any European criminal investigation, biometric data and arrest warrants, meaning terrorists and criminals could flee to the UK before they are identified and get out of jail that way since the country made itself unaware of the criminals - and couldn't be apprehended there either.
And your historical revisionism is just laughable. English liberals maybe didn't want those things, but back in the day, their fraction was about as big as the British pirate party is today. As a whole the British people enjoyed mostly those things.
