> If it's too expensive to create employers, there's no competition for workers.
Employees working in a manufacturing facilities in e.g. China and Europe aren't competing for the same jobs. There's one set of standards for employees there, and there's another set of standards for employees here.
We can't compete with that because we've decided that workers shouldn't be driven to suicide while they don't always share the same reservations and deem waivers, "safety netting", company-provided help hotlines, prayer sessions and "no-suicide pledges", to be an acceptable solution to the problem.

What can we do other than add protectionist rules?
> Only regulations can solve this.
Agreed. And if EU enforces such regulations while China doesn't, for example, we need protectionist rules in place to ensure that they can't undercut us by killing our planet.
