It is not so much a mindset as it is a fact. Our family farm will offer $8-12/hour for field help. In addition to that, we will provide you with transportation if you have none, and we will feed you snacks, a good lunch, and everything you might want to drink during the day. There are few takers. Why do you think that is? The pay is excellent for this area of the country.
The pay may be excellent, but what about job security? What about becoming part of the operation? My own family ran a dairy and truck farm, and there wasn't much room for outsiders to become part of the operation, to be able to contribute to growth and prosperity of the enterprise, to invest in the place, and to share in its growth -- or decline. All the farm hands were paid a fixed price by the hour, or by the bushel, or whatever.
For some people -- like me -- just "doing a job" isn't enough. Oh, I'll do piecework when I have to, such as when my consulting business had the bottom drop out of it and I became a security guard temporarily to keep money coming in, but as soon as I found something better I was GONE. Which makes me a poor fit for your outfit.
A very good employee than can help this operation prosper, and even grow, has a great chance to become a part of something that pays higher and offers better benefits. Apparently we are not like your family’s farm.
