The tragedy of the commons: companies acting in their self interest at the expense of the industry by drying up the workforce pipeline. The next generation will pay, like when America stopped producing hardware.
It has been like this for decades by now, and your precious government loves this because they also consist of old people who hate the younger generations. Any and every time the government intervenes it is to stomp down on the youth and nothing else.
Unfortunately, the government intervention will, if anything, probably just be to increase the number of Visas granted. It's the easiest and fastest fix.
This is cause for government intervention.
