Brexit effects were obviously not understood

I think it is impossible to deny that Brexit proponents had no idea of the complications that it would involve, and that the country is now paying the price of populism encouraged by the ill conceived politics of Rupert Murdoch (and to be fair, some other British media owners whose motivations for being pro Brexit were not always clear.)    

Here's a list of Brexit problems I've been noticing lately:

Car industry in Britain could be in big trouble.

So could aviation.

Fisherman might be able to fish more, but most fish eaten in Britain are likely to get more expensive, and British fishermen might even earn less.

Universities could get less research funds.

Yes, the NHS is about to get more money, but from an increase in taxes, not from the claimed Brexit dividend.
