Isn't the correct response to the sham hirings to regulate that jobs are posted on a gov-run board for some period of time, ~30 days, before you can claim no qualified workers? That seems more reasonable than turning the spigot off entirely.
Perhaps. But given the volume of abuse that appears to be out there the tactic is more turn it all off then selectively back on where appropriate.
Thats obviously extreme but given the abuse in the status quo it’s hard to defend what was going on and whine about this now. Some folks are obviously angry, but that anger is better directed at those that were abusing the system not those trying to fix it.
Only if that job board was an actually useful and common source for genuine hiring. If it becomes “these companies are checking a box, don’t bother applying” or “these companies are considering an H1-B application, flood them with resumes”, neither of those is helpful to qualified workers who actually want to find a job.
