by greedy US-based corporate owners who refuse to pay US workers what they rightfully earn.
They love poorer economies because the people there aren't able to demand fair treatment. Taking time to research will teach you these US-based companies even have resorted to paying local "talent" for barbaric brutality to torture, terrorize, then murder any workers' leaders who dare to try to get fair wages, safety standards, retirement, and humane conditions at their jobs.
Murder, torture, terrorism has been used against US workers in earlier times against US workers, relentlessly, as they spoke out against all of the above as well as child labor in factories before somehow unions were finally able to win enough power to make it too expensive for greedy industrialists to keep harming and killing them for resisting slavery and barbaric abuse by greedy owners.
Best wishes to the workers of Mexico. In time, you WILL win after wearing them down over generations. They are outnumbered.
