The violation is that someone took their land or other property by force, not that someone built a factory and offers them a job.
Survival pay is extortion. Beggars can't be choosers. A man with an empty stomach is not a bargaining man. Arguments about choice regarding a starving man are dishonest arguments.
If you truly want to hold that view in your head, then you must also be saying that the hungrier a person is, the more immoral it is to offer him a job. So the hungry man is unable to get a job, lest his employer be called an exploiter by you, and therefore he becomes either a parasite or dead.
You're no saint.
Sorry, not even close. Not in the same ballpark, not even in the same universe.
