Britain is ALREADY part of the WTO. Therefore, regarding tariff negotiations with other economies (China - billions of people, India - billions of people, Africa - billions of people, NAFTA - a billion or so, the Commonwealth (if they forgive colonial history) UK can either keep the tariffs they are under with the EU, raise them, or
they can lower them AND lower corporate taxes.
I really don't know what the terrible panic is all about. Brexit is about leaving a safe, very large but over regulated protectionist market, to try its hand in the global market leaner, cleaner and more competitive. Paradoxically, economically it EMBRACES globalisation. Yes it is a risk.
But please don't call Leavers stupid or [insert ad hominem insult], they do actually understand what the issues are.
Do you know that Africa, that desperately poor continent, produces nearly all of the cocoa of the world. Desperately poor people, growing cocoa and harvesting it by hand (including child labour), and putting it into sacks to be sold on the commodities markets. - They get 2% of the wealth of cocoa products? Two. per. cent. That is colonisation by any name.
Why can't African cocoa producing countries set up chocolate factories and chocolate processing plants and GET THE VALUE ADD from their own manufacturing processes instead of being exploited like this?
The reason? World and especially EU tariffs that block manufactured goods from coming in. Chocolate only gets manufactured in Switzerland and Belgium! (and a few Quaker families in the UK in the past) Same with coffee. The EU has over 100 tariffs for coffee.
Well, Britain could deal better with Africa, which is a huge and growing market.
PS Mendelez which now owns Nestle and Cadbury's is reducing the cocoa content of its products and increasing palm oil to keep the mouth feel. (Lindt doesn't use palm oil)
Imagine if Africans were able to supply the world with proper chocolate and reap the rewards of their own resources.
