I was once offered a job by Dyson, at their Malmesbury HQ, but I wasn't going to move to a town with a single major employer (and very limited job prospects for my then-partner were she to accompany me) so I turned them down.
Turned out to be the right decision, because shortly after they moved their HQ to Singapore.
Doesn't help that the town is in a train desert.
Rural England (which is not exactly Rural by US or even France standards) suffers from a self-perpetuating brain drain. Unless you're on a commuter line into a city.
