I'm not sure of the point you're making. Or cyclops, come to that. Sorry.NHS medical staff nor the police are poorly paid, and as for the other occupations you mention they are all career choices, no one is or should not be told what job they do.
Some jobs are more risky than others for contracting covid,but all people who provide a service to keep these occupations working like mechanics,electricians,joiners,tyre fitters and hundreds more are all if not front line workers are certainly key workers.
Unless the Bame community are working in sweat shops,is it not about life styles and health rather than occupation.
