Skilled farm workers wont exist unless they are paid big money.
I hear what your saying, and agree that everyone worth employing should be paid a fair wage commensurate with their ability and comparable with 'other industries'.
But 'other industries' are mechanising faster than agriculture, because they have easier processes to automate, and for our lifetimes at least there will be a lot of people replaced by CNC / robots / AI rejoining the labour pool, and who will be able to bring transferable skills and life experience to 'farm work'. Don't forget the hundreds of thousands of people who worked on farms in their youth, and left for better money and 'bright lights'. Their early experience hasn't been erased by half a lifetime elsewhere; think of the amount of lorry drivers who started out working on farms who are going to be the last generation to sit in a truck cab. From around 10 years time, these men (and women) will be knocking on your door, as they know every good approachable farmer in their county, and your number is already in their phones
