An example from history - which I have chapter and verse for, because a close relative was there.
Montgomery of Alamein was an astonishing snob - haughty, patrician and intolerant. A member of 'the ruling classes' by birth, education and inclination. Anyone with less likelihood of empathising with a welder from Hartlepool is hard to imagine.
His insight into what his men needed was, however, beyond compare - as was his iron determination to get it for them. As a result they adored him and would (and did) follow him to hell and back.
You don't have to be 'of the masses' to fight 'for the masses'.
