Exactly. That is one of the main reasons for Brexit. The EU encouraged countries to concentrate and specialise in industries and, particularly during the Thatcher years, we closed down our main heavy industries, which stopped us being as self reliant as possible.
Had we continued in the EU that would have just become worse and worse, as years went by, but we now have a chance to stop the rot and diversify.
Do you seriously think that Brexiters thought that would be achieved overnight? Our main strengths lay in our small and medium size businesses and companies set up by our entrepreneurs, and they should see increased opportunities and an increased domestic market available to them, with far less protectionism and senseless international transfers of essentially the same products.
Most of the large companies that buy up our existing brand names are in fact international and multinational, with shares owned across the globe. BOC was mentioned earlier and they are owned by Linde plc which is described as having "roots and history in Germany" - It's headquarters is however in Dublin and it is quoted on the NYSE so any of us could buy shares and own a part of it.
