I think we're at a really interesting inflection point in macroeconomics.
Before the Great Depression, Mercantilism was the prevalent theory (in the west...) of how a good economy worked. The world wars and that recession put paid to that. Keynes happened, sweeping it all away.
Until the 70s, Keynesianism was dominant, which was toppled by Monetarism, mostly off the back of the likes of Hayek and Friedman, that
Negative Liberty was freedom, limited state is the right way to go. Captured by Reagan's joke, "The top
9 most terrifying
words in the English Language are: I'm from the government, and I'm here to help.”"
I think the financial crisis 10 years has clearly demonstrated that's an insufficient way of approaching the economy. And there are enough examples where it has been proven to be utterly nonsense, China being a great example of absolutely phenomenal, sustained, long term growth.
In parallel, following the collapse of the Soviet Union as an existential threat, Globalisation really kicked into high gear, the WTO's admittance of China being a key changing point there. China's emergence (and to a lesser degree, India, Vietnam and a few others) also kinda messed with the west's economies. Those closed loop balances that would previously have pushed up inflation and wages when demand rose, no longer did so.
I now think the tide is turning against purist free market monetarism and there's a recognition that globalisation has had major costs as well as huge benefits.
This isn't saying I'm anti globalisation, I'm very pro globalisation.
I don't think the losers from it have been even vaguely compensated by the winners and governments haven't been thoughtful about how you deal with the hollowing out of sectors that get offshored and decent career paths from manual labour to a decent middle class living.
Additionally, politics has turned into what you're against (IMO, an outcome from an ideology of negative liberty) rather than what you're for, how government will make your life better in tangible ways by acting in the collective good. Not surprisingly, this is called
Positive Liberty.
Labour should be the party of positive liberty, here is a way that things are better when the government comes to you and says "I'm here to help". But we have to learn those lessons of the failure of Keynesianism. The solutions of the 50s, 60s and 70s will not work now and are likely to end in the same sort of failures they did in the 70s.
I have some thoughts on what those solutions might be, but I've already spent too long writing this post...
