The logical conclusion of the scenario being floated here is that if enough workers resist their own exploitation, the "job creators" will take their capital and go... somewhere. And then there will be no jobs.

(Obviously I'm being facetious. There will, of course, be jobs. And also, a lot of capital owners sitting on the sidelines, debt payments incoming with no income stream.)

Still not even remotely comparable to owning human beings as property.

Regardless, the government cracked down on this behavior (which affected 8 companies) and it stopped in 20009 as per your link.

It's still going on now - they just use a third party to help them collude.

What third party is enforcing an anti-poaching agreement? Can you back up that claim with evidence?
