Why Do We Think Slavery is Evil?

[Rhondazvous]

First of all, it is difficult to know without accurate information of what was really going on those millennia ago.

In those days, most of the 'slaves' may have been just as happy or happier as a 'slave' with room and board as long as they were treated well.  Even if they were not 'slaves', and were working for someone, they may actually have been treated worse by an employer than a master and maybe not even have as good room and board as the slaves.  They did not have unions in those days so, IMHO, six of one, half a dozen of the other.

Now days, how much better off is a minimum wage worker than a slave?  Is slavery really gone?

No, the question doesn't require that we know what was actually happening back then. It is a matter of perception not reality. The question is where did we get the idea that slavery is evil since the scriptures don't condemn it. Since the biblical god doesn't exist, we know right away that we're not talking about what happened, but about the writings as they came down to us.
