They didn’t say we could.
They said industrial farming is more effective per manhour at food production.
And it is. There are obviously further complexities to have everything else in a modern society, but that doesn’t change the fact that even modern productivity increases aren’t decreasing work loads for some reason
It was in response to my saying that you cannot support a large population via hunting and gathering. You need to work harder than that. It is only more food per hour of work if you are talking about a small population. There is a point of diminishing returns and then it gets harder and harder to feed a growing population via hunting and gathering.
Nobody is proposing we switch to hunter-gatherer jobs, we’re saying that the jobs we’re currently doing are producing extreme excess and that excess is either wasted (fast fashion landfills, dramatic food waste) or just hoarded by the capitalist class.
We can support our current population with our current technology and work a lot less.
Anyone that is unemployed could be taking some of your work hours. Many of our jobs are redundant. A different economy can be created where we all work way less than we do while retaining our quality of life.
To say we can’t is to buy into the propaganda that we need Musks and Bezos’ or we’d be subsistence farming. There are other things in between.
Why would farmers in impoverished countries want to retain their way of life?
