1tisILeClerc - "It is obvious that most on here don't give a damn about theoretical or even practical economics."
You are correct, most people don't give a toss about theoretical or practical economics. I'll tell you who does though, the people who operate businesses and factories. They do this stuff all day, every day. It's pretty much all they think about, the best, most efficient, lowest cost way of doing things. Profit. Profit. Profit.
"The issue is far wider than this and arguing the toss about buying a bolt from Sheffield or Okinawa is 'best' has no relevance to those who are rightly concerned and in some cases terrified that supplies of medicines that are essential to keep themselves or loved ones alive are being threatened in any way."
The fact that most people don't give a toss about practical economics is why they should not go round spouting fear-mongering bollocks such as the above. Claiming, without any grounds whatsoever, that factories will relocate, medicines won't be available is utterly irresponsible fear-mongering.
Leaving aside Brexit, do people worry every day about whether there will be any food in the shops when they go to do their weekly grocery shop? Do people worry whether the pharmacy will have their medicine when they go to collect it?
In the ordinary day to day world, there is nobody centrally planning all of this right now. Nobody. The market provides. The market ensures that bread is in the supermarket when you go to buy it. No bureaucrat sat down and phoned the bakery factory and said that 1tisILeClerc buys 2 loaves on a Saturday morning so make sure you deliver them to Sainsbury's in time.
The market is currently supplying all we need, food and medicines.
There are factories who produce medicines. They sell these medicines in order to make a profit. They export these medicines worldwide. What do you think these companies will do post-Brexit? Cut back production because they don't want to sell to UK customers? Why? Will there be a boycott? International sanctions? There are customers in the UK demanding product as they have been for decades. The same customers, buying the same things for the same price and making profits for the medicine supplier.
Are there laws that will suddenly make it illegal for the company to sell to UK customers? They sell worldwide right now so what is the problem? There isn't one. It's all fear-mongering bollocks and they whole lot of you should just stop it.
You remainers are just sore because people didn't agree with you and thus you run around like chickens with your heads cut off screaming that the sky is falling in. It's pathetic and laughable except that clearly some poor souls believe you. I hope you feel good about scaring sick and vulnerable people.
