As a society we should prioritize the protection of people. I recall how the Swedish police announced at spring a few years ago that they would then stop all further investigation at construction work places because there were so many human trafficking violation at such places that just going to a single construction place would drain the budget to the point that they could do any more human trafficking investigation for the rest of the year.

I suspect the news article was a bit of subtle protest by that police department, but it kind of illustrate how low we as a society is prioritizing protecting workers. Some people in the construction industry has also came out saying that construction as an industry would not function without the cheap labor that human trafficking contribute. It should be a major alarm clock that protecting workers from the most basic of threats, ie threat of violence and/or threats by the employer to not pay the employee. Some of the enforcement should land at the consumer who benefit from the situation, which would require companies to insure against shady subcontractors.
