From having worked with farmers, the actual logistics of running a farm are very complex. Farming's no longer an easy job because the demand for productivity means you have to harness a whole stable of technologies and understand to some degree advanced finances, floral biology, geotechnics, and meteorology. And yet farmers still get paid little relative to the breadth of knowledge and skills required for running a farm. It's just that farming is still considered a blue-collar job because it was the domain of the poorest for millenia, where as software engineering in any form is relatively new and thus specialized and so considered white-collar.
