"Why does everyone ignore the fact that <selling your kidneys> is voluntary?"

Some business arrangements are exploitative by their incentives, even if they are "fair".

[LyndsySimon]

I'll take that bait.

What exactly is immoral about selling one's kidneys? Do individuals not own themselves? Are they capable of using or disposing of their own property as they see fit?

If your argument is that people who are forced into such decisions by economic necessity are not capable of making rational decisions, then what criteria do you use to determine if someone is able to make such decisions for themselves? If they fail to meet that bar... who makes those decisions for them?

[jahaja]

Why do you think it matters if a forced decision is rational or not?

Working at Amazon != selling your body parts.

Some things are immoral and necessarily harmful, working for Amazon is not one of them.
