When comparing with places like Czech Republic, people often forget that most of this area in "Eastern Europe" (this isn't Eastern Europe really) was very well-industralized until the mid-20th century when things went very wrong.
So it is true, places like the Czech Republic have done well versus the UK...they have good policies in place, they are doing sensible things. For some reason though, the comparison is never made with places like Spain or Italy, most East European countries are now ahead of them and Britain is still ahead of them too. Even more strangely, no-one is suggesting that we should be more like these countries either...that we should be friendly to business, that we should limit immigration...strange, isn't it?
People outside the UK talk a lot about Brexit, the reason why it isn't really mentioned outside Westminster in the UK is because it isn't that important. We don't export much to the EU (we consume far more), it isn't a huge consumer market, it is shrinking, and there has been no real noticeable impact...even in industries that were going to be "decimated" (such as meat processing)...it isn't happened. There has just been no real impact to speak of. The only exception was NI, which was a situation designed by the EU in order to place pressure on voters ahead of the 2019 election...which didn't work, and which has largely been unwound now that the EU has seen sense (and after several terrorist attacks in NI largely due to, well justified, fears that the EU was motivated by Ireland's desire to seize their country). After 2019, all the rhetoric basically disappeared because all the people pushing for a second referendum discovered they didn't have a job anymore (and everyone else who kept their job, said they never really supported a second referendum at all).
