The cost of housing is a big problem, and no government of whatever colour has had the guts to do anything effective about it. We should copy Denmark, and ban any foreigner from buying property unless they’ve actually lived here for 5 years. London (for starters) is full of new build flats mostly left empty, having been bought by wealthy people from Malaysia/China, etc. as a safe place to park their money.
Having said that, the cost of housing is a similar problem elsewhere - a Swedish friend tells me how prices have rocketed, and it’s long been a problem in Australian cities, e.g. Melbourne, where a friend’s dd and her dh were unable to afford to buy any home even 10 years ago.
You can still buy a cheap (by U.K. standards) house in many parts of rural France, but that’ll be because local jobs are very scarce.
As for the US, of course some areas are cheap by U.K. standards, others are not. My sister used to live in Cambridge, Mass. where prices were not far off my area of SW London, and is now in Cape Cod, where they are sky high.
However having lived abroad for many years I still wouldn’t want to live anywhere else. As for weather, of course ours could be better, but at the same time we don’t often have the extremes of many other countries, not to mention several droughts (both times I’ve visited Oz there was severe drought) and truly terrifying wildfires.
