That’s the real tragedy of Brexit, and something that Brexiters take a perverse delight in… Planes didn’t immediately drop out of the sky when the UK left the EU, metaphorically-speaking. Instead, we’re seeing the decline of a country due to gradualism play out before our eyes, or death by a thousand cuts, if you prefer… or boiling frog syndrome.
Those potholes didn’t occur because of Brexit, they were caused by the cold and wet weather in the UK, plus heavy road use. However, since Brexit, they aren’t being repaired as quickly or in so many numbers because of pressure on local government budgets, which is due to decreased funding in real terms by central government, which is a result of a poorer economy.
The cost of living crisis facing people in the UK is driven by high inflation (I’m going to scream if I hear another politician wrongly infer that a fall in inflation leads to cheaper prices…!), notably caused by food and energy. Over half of the food the UK relies on to feed the nation is imported - thanks again to the cold and wet weather in the UK. Non tariff barriers introduced due to Brexit have caused retailers to increase their prices to offset the higher costs to import food. This has a knock-on effect on wages, which in turns leads to higher prices, etc…
Brexiters usually at this point shout about Covid, or the invasion of Ukraine, or ships being attacked in the red sea, etc… Those things all admittedly had an impact too. But the Brexiters don’t like to admit that Brexit too is having a negative impact, and unlike those other events, it’s not going away.
Unfortunately, as demonstrated by countless vox pops, a proportion of the average man (and woman) on the street seems incapable or perhaps unwilling to join the dots however.
Edited to Add: actually, thinking about this some more, I wonder whether it’s perhaps not an unwillingness to admit Brexit was a mistake, but moreso that people saw how divisive it made the country and so are unwilling to reopen that particular wound just yet.
