To sum up the article, businesses are making ridiculous demands and expecting to pay prospective employees marginally above nothing. Aside from the people posting these job ads, nobody is really surprised.
But if anything, job "requirements" in postings have been getting even more absurd and persnickety in the last 10 years or so. Are employers simply not adapting or is there something else more complex going on? I suspect the latter.
If by "good people" you mean desperate workers willing to work for peanuts, then the cost is almost nonexistent. And that's the problem. Since real workers don't like to be fished.
Folks doing the interviews know what they want and ignore the rest when interviewing, but as the text of the job posting is a poor way to gauge real requirements in an automated / statistically significant fashion. My 2c.
