Our economy is one of the strongest in Europe and our unemployment level is almost certainly the lowest.
Considerable inwards investment has been happening for several years.
Our economic growth is excellent and has defied the pre-Brexit referendum projections. The pound is still in the right place compared to the Dollar. A lower exchange rate to the Euro will enhance our exports post-Brexit and make it more difficult for European countries to sell to us (is that what the EU actually wants?).
We have a low-tax economy which many other countries would love to have.
I can remember when we had a Labour Gov't in the 60's & 70's. Basic income tax was 33% and corporation tax encouraged foreign companies to invest elsewhere. Investment in UK industry was in organisations like British Leyland who never made a profit - well, they didn't need to as we all funded them from our high tax rates. Unemployment increased and this country became the poor man of Europe.
Brexit does not frighten me, but what does is a possible neo-Marxist Labour Government led by Corbyn and his fellow-travellers. He might well make us all more equal - all more equally poorer, more taxed and more personally regulated.
