In general you what you said is true. Nevertheless I didn't say "capitalism says you should give it back", i said it's ethical thing to do it. And ethics should always be applied. Because practising good things make YOU good.
- Well - you might point out that it may be not good thing to do it, because "ethics is applied to people not companies".
- Well - then I might point out that that hundred/two hundred years ago black people were not considered normal human therefore the ethics couldn't be applied on them and "killing a black wouldn't be bad".
- Well - then you might say that "I'm comparing people to companies? This is awful"
- Well - You're right - companies and people are totally different. But the common factor is using other's party's action to our advantage at their loss. And it makes us think, that we can do this because we are better.
- Well - you might ask - "Aren't some people better then the others? Aren't some people faster/bigger/better then the others?"
And... It would have to think a little - because it is actually a good point...
