Regarding the first video, third world countries are not disregarded because there is no profit to gain there, exactly the opposite, there are huge investments in third world countries precisely because it's a rising market where new players can prosper without giant corporations controlling the market.

The helicopter guy example is not of Capitalism but if greed, the capitalistic logic here is that he has a right to individually consider his choice in this situation and so do his future coworker and clients on whether to work with him at all.

The entire video talks about Capitalism as if it's a standard way of thinking, a bottom-linism when we all know that some people do choose to give millions to charity, not as an anti capitalistic action but because Capitalism doesn't stand in people's way, if people want to give charity they can, if people want to evaluate charity-givers they do.

Also it makes zero sense to put so much responsibility over people's lives on Capitalism, simply because Capitalism doesn't hold the power, people do.

Sorry, I won't read the book, I'm sure it had much valuable information but I asked a specific question reacting to a specific argument. If you have read it, I'd be glad if you could give the relevant quote or at least direct us to an exact page so we can share it here with everyone else.

About the second video, it seems to show what a capitalistic society would do to preserve itself.

It doesn't address that at all, as if communism is synonym with pacifism - so I'm asking you - how do you think the communist side of the island would react if demographical changes were to threaten their survival?
