Someone upthread said 'it'll get better'. Our government chose the most extreme form of Brexit and these are the inevitable consequences of that choice. Our government inflicted an extreme, Ill-understood, almost not at all planned for, shock to our economy, overnight. There is a flat refusal to acknowledge that, and there can still be no logical or rational discussion of that because Brexit was to have only positive and no negative consequences.
This is our Brexit, we have to live with this, the inevitable fall-out, and a government that simply does not understand modern trading conditions.
It is naive, stupid, ill-informed and zealotry, all those or a combination of them, to think that somehow this it will all sort of sort itself out. It won't, not if this extreme expression of Brexit continues to be pursued and all consequences are denied or blame for them placed elsewhere.
I would suggest people have a look at Sam Lowe, David Henig, Dimitri Grozoubinski, amongst others, to get some grasp of what a shock to our economy this has and will continue to be.
