A couple of day ago I was a trailer for a Charlie's Angels reboot on it and recognised British accents.
These accents belong to actresses called Naomi Scott and Ella Balinska.
Wikipedia tells me both were born in London.
Scott's mother, Usha, was born in Uganda, of Gujarati Indian descent, and immigrated to England at a young age and her father, Christopher, is English. Balinska is the daughter of English chef Lorraine Pascale - born to Jamaican parents - and Polish entrepreneur Kazimierz Balinski-Jundzill.
I find this immensely cheering. As Keynes would have it:
Even apart from the instability due to speculation, there is the instability due to the characteristic of human nature that a large proportion of our positive activities depend on spontaneous optimism rather than mathematical expectations, whether moral or hedonistic or economic. Most, probably, of our decisions to do something positive, the full consequences of which will be drawn out over many days to come, can only be taken as the result of animal spirits—a spontaneous urge to action rather than inaction, and not as the outcome of a weighted average of quantitative benefits multiplied by quantitative probabilities.Which is a round about way of saying that m way of saying that - over the long term- it is miscegenation that will save us.
