Job Postings requiring minimum experience-Part 2

What is the job market coming to?  Look at one of the duties, below, I found in a job posting.

Prepares mechanical detail drawings by developing applications and calculations of castings, forgings, stampings, machined components, gears, cams, bearings, belt and drive chains, splines, linkages, dies, jogs, hydraulics, and pneumatics; producing fit specifications and geometric dimensioning and tolerancing (GD&T); analyzing force systems in equilibrium, involving loaded beams, columns, trusses, and riveted and welded joints, and internal stresses of loaded members; resolving conflicts between options.

This posting states that the applicant should have 1 to 2 years experience.  When this part of the 'duties' list is taken as a whole, there is no possible way a person with 1 to 2 years experience can know these things to the degree the position would require.  Actually knowing and applying GD&T principles alone takes more than two years.  Analyzing force systems in equilibrium involving...?  How can 2 years of experience give you that knowledge. 

I have no doubt that there is a definite disconnect between hiring managers and HR.  Or, the other possibility is that company's are now trying to get the most they can for as little money as possible, and I point to the experience required factor in that regard. 

I am at a loss to understand how these companies work.  The adage that "you get what you pay for" seems to so true here.
