You're ignoring the fact of globalization. Corporations and their consumers are getting more and more sophisticated at targeting and exploiting the countries with the worst labor laws. Multi national corporations are getting more sophisticated at evading scenarios where particular host countries (i.e. post-industrial nations) attempt to curb their exploitation.

This is a real and scary problem. It is not without precedent--the horrors perpetuated by the unfettered corporation-states during the colonial era are an example of the results of 'self policing', which is too often society's answer to how corporations should be regulated.

This makes for a situation that is worse than that faced by the first rounds of Industrial Revolution countries, for labor movements have little power when economic benefits actively bypass countries with more regulations and flow to the most corrupt and exploitation-friendly countries.

Perhaps we cannot (yet) create a utopia where every human who is born has a healthy and labor-light life. But we can refuse to accept the 'actual realities' and try to prevent scenarios where wealth is distributed to the exploiters and not the exploitees.
