A 'Lived Experience' of One?

Kwame Anthony Appiah makes a very good point, when suggesting that politicians are, perhaps, relying too readily on 'lived experience' to guide their thinking (https://www.theguardian.com/commentisfree/2020/nov/14/lived-experience-kamala-harris). Pretty obviously individual politicians may 'share' some experiences (such as being racially discriminated against) with sections of the public, with whom they have characteristics in common. Because they became successful politicians, however, their 'life experiences' are generally atypical. Appiah does not appear to be saying this to negate legitimate concerns but to point out that features like socio-economic background and educational opportunities will drammatically alter the 'lived experience'. It could, for example, result in racial discrimination being 'felt' differently by different people. He also points out that, for example, being a public prosecutor, can result in a person developing left-wing, liberal or right-wing tendencies. Thinking back to my own 'lived experience', I don't think I have many insights to offer to all other white, working class, Mancunians with a difficult (non-Grammar school) educational background. Not many others were 2 metres tall at the age of 11 years but managed to 'claw' their way into university (at a time, when only 2% of the population, usually a largely Southern and public school-educated cohort, got this experience). Whilst not claiming to be unique, I will admit to being atypical. 'Lived experience' does seem to have limitations and politicians should not think it actually gives them direct insights into how everyone else feels.
