//You then decide not to attend the market and spend the £10 saving on your healthcare – only a fool would claim that they have benefited from the above scenario – but that is what Brexiteers are doing.//
Not a particularly good analogy. You left a bit out. Did the sole trader simply give up trading, or did he take his business to a different market?
//I need a long term stay visa valid for only six months to reside in our cottage in Normandy if I want to stay for more than 90 days in a year.//
Then get one.
//My son can no longer just hop over the channel to do his self-employed job, he has to get visas for every job. Before brexit he did’nt.//
Then he needs to adjust – or confine himself to the UK and Ireland.
//my daughter sells crafting supplies from her online shop. It is now easier for her to sell to Thailand than to the eu because she needs licenses for every parcel she sends and the recipient has to pay 20% duty at point of entry in any eu country.//
Then sell the stuff to Thailand. Surely if it’s easier to do so that’s the way to go – trade with nations that don’t go out of their way to make it awkward.
These are piddling trifles. The idea of Brexit was to change the UK’s direction, not to keep it the same. The idea was to diverge away from an protectionist, over-regulated, shrinking market and seek opportunities elsewhere. What did your son and daughter do to adjust between 2016 and 2021?
//…with things costing more and inflation being higher,//
Tell me how Brexit has caused inflation here, but it hasn’t caused it everywhere else it has occurred. The UK Consumer Price Index for May was 8.7%. There are twelve EU countries with an inflation rate higher than that, some considerably higher. So why do you blame the UK’s lower inflation rate on Brexit, whilst not mentioning those countries – who are still EU members? What’s so special about the UK’s inflation rate that it has been caused by Brexit (apart from your obsession with the topic).
