Lack of Social Mobility in the Air?

Concern has been expressed about social mobility stagnation in the UK (https://www.theguardian.com/society/2021/sep/28/lack-of-social-mobility-in-uk-risks-fuelling-populism-says-fiona-hill). The children of rich people generally thrive, whereas those of poor parents often fail to achieve. Initiatives have been set up to try to give children from poorer backgrounds more opportunities. There is a need, however, to recognise that such children often carry subtle, lasting handicaps. Studies have demonstrated that, in the UK, there is a strong correlation between poor air quality and child poverty (https://www.theguardian.com/environment/2021/dec/28/labour-highlights-link-between-child-poverty-and-air-pollution). Poor people tend to live in cheap accomodation in areas with busy roads. Their children will consequently live and attend schools in areas with high air pollution. Most of the 50 UK locations with the worst air quality (often related to vehicle emissions), also have the highest rates of child poverty. Vehicle emissions include nitrogen dioxide; carbon monoxide; ozone and sulfur dioxide, as well as particulate matter. Poor air quality reduces life expectancy and damages both physical and intellectual health. It's consequently not just the fact that the parents of poor children can't afford private tuition, they are damaged by the air they breathe. Hardly remarkable then, that many don't go on to attend prestidigious universities and/or move up the social strata into professions. Banging on about encouraging aspiration, without also cleaning up the air that poor children breathe, seems a bit futile.
