There’s three things, pick two. I use it often in engineering, where the corners of the triangle are Cheap, Fast, Good and you can only pick two. Managers always, always want to pick all three, just as well as the UK seems to want to pick now. Have your pie and eat it is the motto of the day.
I cannot even snigger at the stupidity of Britons who voted to leave, since I have no doubt that had Czech Republic had a similar referendum, our results would also be similar. Because despite the objectively measurable fact that we are much better of in the EU than we were outside it, a lot of people yearn for the good old days.
Good old days that never were. If I were to pick only one reason for why EU is a massive political success despite all its flaws it would be this:
There was not a war between members of EU for two generations. Prior to that, the whole EU history was stumbling from one war to another, and the scars from those wars still did not heal.
