> I don't know the industry but perhaps the modern job is easier to get and seen as lower status than it was in the past? I'd say there's more technical skill (certifications and iso standards) to adhere to in cleaning today, than 30 years ago - and each worker clean larger areas (and probably works harder than 30 years ago, suffering under tight micromanaged schedules). That's my impression (though mostly in Norway). Note that cleaners might be better, more efficient and doing a more demanding job, and still have lower status...
