honestly, there are no obvious answers to anything.
But if I were in charge, I would tackle the following:
Media literacy - make it a core function of the curriciulum to educate about critical thinking. I was always taught, "read a story in one newspaper, then read that same story in three others - then you'll start to uncover the reality without the bias". In today's age of disinformation, I think this is a fucking CRUCIAL thing we need to do. The impact of the billionaire media barons is terrifying, not to mention the tech bros literally force feeding us false algorithms.
Immigration - Ultimately, I'm a lib dem voter at heart, although I did vote labour last election. We have to acknowledge that there are big concerns over the levels of immigration. Why can't we move to a points system whereby we encourage those who have the skills we need? Other countries do it effectively. I absolutely agree we need healthcare and highly skilled professionals - but the "unskilled" migrants, e.g. the deliveroo drivers, the uber drivers, is where the problems occur because they simply won't be 'putting back into the pot' - in fact, if they are using the NHS, using schools, even driving on the roads - that's not being a net contributor.
Education - ironically, I think the curriculum needs to be reformed (yet again!). It's not fit for purpose anymore - technology has changed so much that the kids don't have the skills for the new jobs that are emerging/will emerge. For instance, we know that the UK film industry contributes billions to the economy - yet the arts subjects have been decimated in the curriculum. More focus needs to be on tech subjects - coding, data analysis, interepretation, AI implementation - this all needs to come before university level.
Housing - I've said a million times. A huge issue is the focus on first-time housing, and not last-time housing. We need developers to build final homes - possibly bungalows, but ones that can allow people to remain living independently at home for much longer. Making hallways wide enough for wheelchairs/walkers, having downstairs bathrooms, removing the need for steps into the front doors - these are all minor things but we know that bed blocking is a huge issue in the NHS. Elderly people want to remain living in their homes and that's why they dont want to downsize or move - but the reality is that in many circumstances, their homes aren't appropriate for their changing needs. There should be incentives - perhaps if you're downsizing, you are exempt from stamp duty.
Taxation - we need to pay more tax. It's simple as that really. I genuinely don't know how you do it. We need to start explaining where the money is going and how it's being used.
