The alternative is called exploitation.
I don' think it matters that it would apply to so called 'un-documented' workers or not, (she may as well have called them illegal aliens), I think she was addressing a practice of employers exploiting any worker.
Of course such a thing may have an odd effect. If employers were required to pay fair wages for all, then they may stop resorting to employing cheap labor, illegals, and your country's unemployed may find work instead.
So in that sense, yes, it makes sense.
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
