Yes, MaizieD, I'd like to see that. One point at a time:-
"If we leap out of the boat and into the water" - leaving the EU is leaving a boat that is safely afloat, has a compass and radar and lifeboats, and that has space for a lot of valuable cargo which we know is saleable for a decent price. We are (soon to be were!) members of the decision-making body, which decides the standards of the merchandise, the rules of trading, and the way the crew and passengers are treated. We get on well with of fellow crew-members (mostly) and we haven't had a punch-up with them for decades. We visit each other's homes without needing visas, send our young people to complete their education in one another's colleges without any bar, We treat one another's illnesses.
"we will be able to swim the Atlantic, storm the US market and sell them all the stuff we don't make any more." Well, that doesn't need explaining. Negotiating a trade deal with the US and that nice Mr Trump will be a doddle - we hold all the aces. Don't we?
"We can jettison all our safeguards on imports, our employment rules, our health service." We'll have to, to get that trade deaL
"We are strong, we are great, we are the champions! We will prevail!" Nothing if not optimistic.
"Let's go back to Tudor times, when we explored the unknown world and began to trade . . ." We WERE among the greatest, then. We were one of the three great trading nations, expanding round the globe, opening up trade routes to the east and West, doing battle, literally, with Spain and Portugal for power and influence over the New World. We did pretty well under Queen Victoria, too, the queen empress, but she is dead now.
" . . with countries who were unable to make all the manufactured goods we were so good at producing," now we don't produce nearly as much, but those countries have taken enthusiastically to manufacturing, streamlining production and improving quality and marketing methods. They don't want to buy our "cheap tin trays" any more - they can make their own, and sell them to us.
" . . countries who were delighted to sell us their food and raw materials at low prices, because they didn't have the expertise to exploit them, . . " but now they have that expertise, and their populations have expanded. They need their food and raw materials for their own people and thgeir factories. They will only sell it to us at a profit.
" . . who had no knowledge of how to negotiate good terms, so we could get the best deals that were going" Since then they have learnt from us how to screw the best price to sell at and the lowest price to buy. They have their own trading groups and their special deals - they don't need ours.
Now point out the bollocks. Don't bother repeating that we will be free - free to do what? We will be no freer than we are now.
