* We do not have enough houses in economically productive areas - look at the OxCam arc, London. NIMBYs keep sapping every attempt at building more houses.
* Terrible childcare - we have to pay about 1-2k per kid for childcare. Go figure out how to have children in a climate where it's cheaper for a parent not to work (if you're on the average income).
* Healthcare - as a naturalised brit I will never understand the sacrosanct nature of the NHS. We plough a ton of money into something that is very equitable but is terrible for outcomes. Most folks who have money I know always tend to go private rather than dealing with a 6 month wait for a routine check up.
Economic reform
* Investment wise - we are funding out deficits by selling our assets to foreign investors. Most of the country's financial assets are seen as safe dividend givers. We have a decent startup ecosystem, but we should invest far more into research, infrastructure to actually ensure there is a boost to the economy.
On the structural - few things come to mind, but can't articulate them super clearly. Hope that helps
