Honestly this is nothing new. Selling commodities of any kind has alwas sucked unless you can do it at scale (which is basically impossible when the limiting input is ones time).

For a short time industrialization meant that the least skilled could produce as much as the most skilled, but as pg argued that was as special case of a special situation. I know of no case where it has happened before or after, anywere.

If you only have commodity skills, the best thing you can do is to go down to the nearest community college.
