But what if you can't find enough people to do farm work? A lot of people work on farms now because they don't have much of a choice. And if you could do easier work but be paid the same as you would on a farm, why not take advantage of that?
With modern farming, 10% of the people can now produce enough food for everyone. And if everyone had equal income instead of the top 1% syphoning off half the wealth, we could globally support a middle class lifestyle by everyone working 20 hours a week, the same amount that hunters and gatherers “worked”.
The only one of those that is hard physical labor is firefighter and it is not the consistent physical labor of farm work. Have you ever even been on a farm?
