I'd quite like to see someone 'sell' being, say, a fruit pricker to someone in the UK these days. I'm sure the residents if the local area will be lining up to do poorly paid (more or less by necessity) backbreaking seasonal work. Especially if they have any form of commitment in their personal life. And even if they don't, presumably at some point they will, or will have some ambition, and fruit picking isn't going to do you that much good in a job market where experience trumps all. Repeat ad nauseum for various sectors. These jobs are there. British people aren't queuing up to do them, through combination of it literally not being viable, to an aspirational culture that rejects 'unglamorous' work (shorthand for anything from well salaried to interesting etc).
The easy answer is attack the Other. Unfortunately the question is difficult.
