Of course, I would like more flexibility in choosing how much I and where I do my sedentary labor, so I might devote time to, say, gardening. But it's easy to forget that humans have spent most of human history trying to escape subsistence farming.
I have worked subsistence farming for a small portion of my life, and I cannot tell you how hard it is, physically and psychologically. That was by choice, as part of essentially joining my wife's culture and family. If I were to do that for the remainder of my life it would destroy me.
Anyway, I'm going to go happily work from my desk 30 ft from my bedroom while drinking coffee likely farmed for about ~$0.30/hour while I make a few hundred times that.
Success and failure are choices. Accepting this allows us to take responsibility for the worlds we've created. Ignoring this is self-destructive act of cognitive dissonance and we pay for it years later.
Do you define human history as the last ~10k years or last ~100k-500k years?
But yes, certainly at least the last 3000 years for most humans have been spent farming to a large degree. But if we are even moderate in estimations of human origins, farming is very recent.
Certainly, some people still live as hunter gatherers. I presume people can deduce I do not refer to them.
You'll end up burn out and hating the job (no matter the job) if the company you work for doesn't give a considerable weight to the wellbeing of employees (at the percieved cost of productivity and raw revenue).
Unfortunately, many of us are chained to the modern way of life.
You can make a lot of money doing many skilled manual jobs in my country. Trades are highly paid and there is not enough supply. Better money than software development.
They often wreck their backs, or develop other chronic conditions. The successful ones stop doing manual work by the time they are in their 40s and move to running their own businesses employing 20 year olds.
A friend of mine just lost a family member a few weeks ago. He slipped on a roof.
This is because often the rules and laws protects still human instead the profits.
ps: Unfortunately I agree with you.
As a farmer, it is funny to see how people react to you based on the current profitability winds. When farming is a money maker, everyone acts envious and treats you like a king. When times are tough, they think you're a slack-jawed yokel.
I expect in that lies the answer to your question: We denigrate anything that isn't, as a rule, making a lot of money. Manual jobs generally haven't made much money in the last century, and humorously the exceptions, like professional athlete, get exempted from being considered manual work.
While I'm not a farmer, from my experience they still call you a yokel when it's profitable.
