I just edited the article, I forgot to expand on that.

I have actually implied that poverty is relative as well, since you can't know what poverty is.

You can have spiritual poverty, monetary poverty, poverty of freedom, or other.

• So you as a 21 century human are richer than a caveman in pretty much all aspects
• But a caveman had more freedom than you, since he didnt have a government

So a caveman could pretty much go into a goldmine and say that all the gold inside it is his. However you can probably not even access 1 kilogram of gold, in the 21 century.

A caveman had an entire forest to hunt from, while many humans today starve to death.

So freedom is also essential, you cannot just say that having internet and mobile phones makes humans more rich than a caveman, because in many ways a caveman had a wealthier life.
