There is also significant cases before and currently in South Korea, namely illegal immigrants working at farms with nigh-slave labour conditions and factory workers in Samsung/Hyundai etc large multinationals
I like how US federal overtime laws specifically exclude agricultural workers.
I cannot imagine any reasoning to do this other than to take advantage of farm workers that are poor and probably do not know English.
So politically, the nation wanted people to have a minimum, albeit pathetic, pay to quality of life at work ratio. But even then, it was okay to explicitly screw at least one tribe of people. And entering 2023, there is still no political impetus to fix this.
Everyone gets screwed commensurate to their organized labor power. Industries of "illegal" immigrants have the least leverage, and that's reflected in institutional legal frameworks
