Your question is coupling a matter of our policy preference, our tactical planning to arrive at that preference, and a hypothetical predictive model. If like some supervillain I had come up with a satisfactory answer to all those questions I would have enacted it twenty minutes ago.
I'm ignorant on this topic; do you mind elaborating?
I strongly suspect it's a variant on capitalism that:
1. Recognises that some industries (utilities, healthcare, etc) are not well suited to market provision and are state funded. i.e. the sort social provisions that many of the nordic countries have.
2. Recognises that extreme wealth inequalities invalidate the key principle that capitalist economics is premised on (that the market value of a good or service closely approximates it's societal value) and therefore imposes much stronger progressive taxes on very high earners to effective cap how much wealth a single individual can control.
> early stage capitalism (lack of regulation and all)
High tax rates (90% in some cases) and all
Academic attempts to identify the optimal maxima of tax receipts, which conservative political operatives will always implicitly assume is "half whatever the current rate is", suggest something on the order of 60%.

I would dispute the premise of the Laffer Curve: that the goal of setting a (high) taxation rate is to maximise government revenue. I think that reducing wealth inequality is a good in and of itself. And especially under a capitalist system that depends on it's citizens having vaguely equal purchasing power to function efficiently.
Assuming that our starting point is our current situation where wealth is very unequally distributed, that is. I would agree with the suggestion that things being too equal, and there being no reward for hard work and/or ingenuity also leads to problems.
Optimisation that tries to balance that trade-off would interest me greatly.
See South Africa for an example. Power production is slowly opening up to market forces as an alleviation to the extreme mismanagement and corruption of the last 2-3 decades.
On the other hand, there are also some alternatives, like "devolution" of state services to the provincial or municipal level. The local Cape Town government is busy trying to gain control over the city's train lines from the government org that owns them, to provide better service.
Returning by right development to the UK is very possibly the single largest policy measure that might enable a way forward, not because it's so intimately tied to the financialization of the economy, but because it's such an enormous capital concentration that its limitations overshadow a lot of other issues.
It may be hard to see it from where we're standing, but the current housing situation is one extreme of a catastrophic ongoing crisis.
The private sector never built any of it. NIMBYs didnt stop this construction. Ideologues whinging about the % of GDP spent by the public sector did.
NIMBYs are just a side effect of the world neoliberals created.
And of course, it made it all worse. Now you HAVE to work in London if you want a high salary.
The only real way to fix the housing is to promote remote work and decentralized companies.
Nobody wants to work in some backwater in the middle of nowhere either, especially if you are young and want to meet new people.
Their system is a much better one than we tend to have in the US, but "All-in on public transit" looks more like Trantor than London. A majority of the TFL system was constructed more than a century ago.
So if you increase the population density, the transit to that focused area will have to carry more people. And it's already at capacity.
If you want to increase the density, then London will have to create new business areas outside of Canary Wharf, City, and Westminster. At which point, the question becomes "why even bother with London?"
You also can’t act against monopolies when China happily won’t act against their own state owned monopolies, which are in an arm’s race trying to surpass us. Falling behind to China is a great way to cause a tech investment collapse.
I think this wouldn't be bad.
Rebuild into socialism?
Rebuild into communism?
Reset into early stage capitalism (lack of regulation and all)?
How do you know that those systems won’t also have their own late stage failure? Case in point, the NHS right now.
(Edit, posting too fast: To the person below who suggested 90% tax rates; the US never had those rates. On paper they did, but they had more and larger exceptions than now, to the point the effective rate never exceeded 45% anyway. This is also why the massive cut was politically palatable - it was cutting the rates to closer reflect the reality. At no point did the US ever have anything close, or even half close, to 90% effective rates.)
