https://www.ft.com/blackpool Seems like it's not paywalled. FWIW Blackpool looks like a heck of a lot of seaside places in the UK. Whatever problems are described in this article are problems all the way around the coast. Visit a seaside town here and it often feels like you're back in the early 90s. There's a certain style that hasn't been updated. Arcades, chip shops, betting shops. Ok the betting shops look modern…
From an Australian perspective the idea that "seaside" towns are especially susceptible to economic decay and being left behind seems quite odd - even in parts of country without year-round beach weather, coastal localities here are usually the desirable places to live with subsequently healthier economies. Are there other countries that have experienced similar patterns of development to the UK?
Other than last year, I can't remember a year in the last 2 decades where going to the coast wasn't such a massive gamble.
Even I have given up and decided to spend a week in Turkey.
