Watch what happens when two monkeys are offered unequal pay for the same task:

😔😢 No More Animals in Captivity, please 🙏🏻😔💔

OK, but please stop these experiments on monkeys.

What an awful mesagge The end of this video with the man saying that this is like Wall Street protests is so wrong.

Proving your point torturing a monkey´s brains, not so great...

Humans are so toxic that not even spare the animals 😂

set them free

This what they still do to black employees in companies. Do same work but benefits not same. What a shame, now you breed frustration & anger.

Test on monkeys to confirm.what we already know. Are you really serious?

This is over 50 years old. It was done a female I can’t remember her name currently. Learned about it in linguistics couple years back. Quite interesting.

Did one of the monkeys play a victim card every 30 seconds? 🤔🤔
