@joecguinan response to Starmer's speech is partly defence of "Corbynomics" as embodying an institutional critique of neoliberalism I mostly agree with, but three further points to make: https://tribunemag.co.uk/2021/02/the-unbearable-lightness-of-keir-starmer
1. The critique of neoliberalism under Corbyn was too often presented as a variant of anti-austerity economics, as @jemgilbert has indicated, which is politically disabling in terms of grappling with Labour’s actual legacy in govt. Austerity is not same as neoliberalism.
2. It’s mistake to insist on importance of 2019 manifesto to Corbynomics, tactically & strategically. Tactically: 2019 was terrible result, don’t tie urself to it. Strategically: 2019 backed away from more radical content of Corbynomics in favour big spending ie classic Labourism
3.He understates degree to which much of “institutional turn” has entered into the common sense of Labour in general - Miliband, Reeves, Streeting from different wings of party have picked up on it. Starmer speech also anti-austerity, but this has issues: https://www.newstatesman.com/politics/economy/2021/02/why-condemning-austerity-won-t-be-enough-restore-labour-power
