I don't particularly care if work visas get harder. Maybe they should.

What should be done is serious scrutiny _before_ someone is admitted. Once they are, the system should get out of their way. A person is working for years at some company, paying their taxes, spotless track record (often not even traffic tickets as they can cause trouble) and yet, they cannot even sponsor for permanent residency themselves. They depend on some company, which has no interest of doing so until the time is close to running out.
