Well, I can very much expect them -- and chose to do business with companies that do care.
But true, the social protection/minimum wage should also be set by law. Only that's a minimum limit -- I expect better than that.
In the end, I don't want businesses that merely say "compete to the full and fuck everything else".
I'm 100% certain that most people will go with "cheapest" or "more convenient" regardless.
Not the best criterion, what most would do.
Especially since it's more like "what most would do given a society that raised them like we do and given them the motives that we do".
I believe most places in the world, even some of the poorest and most desperate set a higher standard than "kill to survive". Given a chance most people will naturally form communities that will try to protect themselves from harm. Destructive behaviour is not a forgone conclusion and as soon as people start to understanding this they will stop being scared of their neighbours.
