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.
