The fact that much of our civilization's functioning currently depends on such slavery is no excuse for us to close our eyes to it. As technology improves, slavery becomes increasingly obsolete.
And when someone recommends helping ex-slaves displaced by technology integrate into free society by giving them resources they can use for that without any strings attached, they are told that this is bad because if they do not work than they do not deserve any money (or in other words, if they serve no master than they do not deserve to live).
So instead they propose a plan to put the ex-slaves back into slavery, but this time doing useless, pointless tasks that no one needs nor wants them to do. Since that's better than having them get anything for free, right!?
I think this explains the whole pathetic fiasco that is "basic jobs".
