It probably the fact that the industry is getting flooded with people who think working in IT is a easy get rich job.

It certainly was 20-25 years ago. Zero formal education besides high school would land you a job 5 times the minimum wage working mostly in air conditioned comfort. Upward mobility was built in, and many of us have leveraged that for even higher paying positions with the gained experience and continued learning of the tech on our own.
