Agree with everyone else, it really depends on your circumstances & where you live but there are definitely broad issues. The NHS is on it’s knees, housing prices are high, childcare costs are huge, lots of councils and schools are struggling despite people paying huge amounts of council tax which then leads to more unhappiness.
I’m similar to you OP in that I love where I live, I love our house, I love the area, we get a lot of time outdoors and live quite rurally so are lucky to have lots of beautiful places on our door step, our local schools are good, so in my standard day to day life I’m happy, but I’m conscious that if any of us were to need A&E, GP, hospital etc we’d quickly realise how bad things are. I’m also aware that even in our village things are changing, there’s a house recently sold round the corner from us that last sold in 2019 for 190k, that same house has just been sold for £353k, no extensions, no building work, new flooring/kitchen/bathroom but none of that justifies such a huge uplift, housing is just becoming unaffordable and it’s happening fast. We’re a young family, both in our 20’s with one child, and we simply got lucky in that we by chance managed to buy our house before the prices have shot up, lots of young families used to buy here but now it’s really out of budget for lots of people which is a shame.
We have friends who moved to the US and have recently bought a home there, it’s huge, 4 bed, lots of land, 3 car garage, swimming pool, for 350k dollars which is around 290k GBP- that price wouldn’t even get you a 3 bed semi where we live anymore.
