Capitalism is on of the worst thing happening to humanity. :( It promotes greed and punishes people who aren't greedy. It makes more problem than it answering problems.
Those people are correct. Capitalism is a reflection of our collective misery. Look at how many people are on anti-depressants today, how many are suffering from mental health issues. Our ability to engineer the world to our advantage is not the problem here, that is something human beings are extremely good at. The problem is that we lack the ability to engineer ourselves.
