Literally! But, jokes aside, how is that amount measured? Software development (which I also had a job doing during my time in high school) seemed quite approachable. I've certainly become a better developer over time (along with everything I've continued with), but I'm still proud of what I accomplished back then. I don't feel that it was out of my depth. I was able to deliver real business value and the employer was happy.
Honestly, I find software development has been one of the easier jobs (in terms of knowledge and ability required) that I have had. Granted, I haven't had jobs in every industry out there. I expect there are easier jobs. But software development does not strike me as one that meets the necessary degree here. If someone in high school can walk into the job and deliver real business value, it does not feel like a "degree required" job to me.
In my opinion, the defining factor here seems to be how desperate employers are. On the farm, we are often quite desperate for help. Timing is critical. Leave the crop out for an extra week and you won't have a crop at all. As such, farm work is considered low-skilled work since employers have no room to be choosy. You take what you can get and deal with what comes from it. It is still better than losing the crop.
Contrast that with software developers, where there is no real pressure to hire people. Who really cares if a feature sits in the backlog for a year? It will still be there next year. That allows employers to be more picky. Don't like your current applicants? Just wait longer. As such, this industry is labeled high-skilled work. If there is any pressure to get the job done, it comes from the competition trying to do the same as you, and they are just as likely to have hiring problems in those circumstances. In reality, the amount of actual skill necessary between these two examples is probably quite comparable.
