That 50-75% will come around when they stop getting job offers due mainly to a dearth of pileous vigor--also known as "poor cultural fit" or "hiring discrimination"--rather than insufficient experience with technology X.

The need for a worker cartel is directly proportional to the relative power a typical employer has over a typical employee. If the only way you can improve your work situation is by changing jobs, you could benefit from a union.
