And by all means make sure our citizens become enthusiastic about picking crops, slaughtering chickens, etc. and all those other lovely jobs currently held by immigrants. Plus insist that the businesses pay high enough salaries so that our citizens will take the jobs, and enable all of us to pay more for the food we now enjoy relatively cheaply. Do that and indeed the rest will take care of itself. Hope you like it.
I'm right, aren't I?
The jobs will pay whatever is required to get people to work in them, and the price of the products will rise or fall to reflect it. It's called "supply and demand." Ever hear of it? Or do you think that you should be exempt from it?
Stop making welfare and unemployment benefits last in perpetuity, and people will take those jobs.
The only reason they don't take them now is because they can earn more money collecting transfer payments.
