Theresa May has just said

Theresa May has just said that a post-Brexit Britain will be the "global champion of free trade":http://news.sky.com/story/theresa-may-uk-is-global-champion-of-free-trade-10656863i.e. of more globalisation, but isn't the effects of this on some being said to be one reason for the Brexit vote and the election of Trump?  I don't think she understands that Britain on its own will be a minor player on the world market compared with the US, the EU (and its single market), China and Japan. The tendency is towards big, regional customs unions which do trade deals with each other. The sort of hard Brexist she and some of her ministers want would be a move in the opposite direction. A Britain outside one of these unions may be able to do deals with Canada and Australia but these are countries with small populations and so small markets.
