It's hyper individualism that is fueling this type of capitalism, the notion that you owe nothing to anyone and other people in society are not your concern, society itself is not your concern, it’s only about what you want etc. It's like a pond, if you follow hyper individualism, you will extract as many fish from the pond as you can, without caring what happens next or others using the pond, and the fish will not be able to reproduce for future generations, others will not be able to get as many fish as they need etc. It needs to be balanced. As you say, there is something in between that can work, we do not need to choose only between extremes.
