For Swiss people old like me, we still remember the exact same misleading articles when Switzerland said NO to Europe in 1992.
Switzerland had to adapt and is going fine today (minus covid). Hopefully UK will do the same.
So while Switzerland is doing fine, they are, at least when it comes to trade, borders and certain security measures like weapons controls, very much a second class member. I'm quite sure that is the opposite of what the Brexiteers intended, at least in my interpretation of their aims.
I'm sure there are also old Germans around who remember the price increases when switching from DM to €. These kinds of things are complicated.
I'm also not sure if these articles are supposed to be pro-EU fear-mongering, or simply a wake-up call to people in the UK to deal with the consequences of Brexit and "adapt"?
