Earlier quoted context omitted.
There are different markets. It's easy to hire full remote juniors on upwork for next to nothing. Hiring a senior staff superhero full-cyber stack-ninja who happily relocates to where you are... now that's not that easy. And thus on the low end you have a market glut and on the high end you have a shortage.
But that's still not a shortage. The government hasn't imposed a wage cap. Employers can just increase wages to the market rate.
Example, you have labor force of 10 people. All jobs have mandatory stay of 2 years. 6 companies have an opening each that pays 1 mil/year. The openings are staggered so 3 jobs are available on odd and 3 on even years (and last 2 years). 50 jobs are posted with a salary of 100k/year. These salaries represent value produced to company and cannot be raised. All applicants have equal chance to get a job they apply to.
The minmax solution is to not take a 100k job because of opportunity cost (you won’t get a chance at the 1 mil job next year). So you have both 40% unemployment and massive labor shortage (56 openings but only 10 viable candidates).
