The surface problem is that capitalism is an artificial form of natural selection (culture) and people fear struggle of any sort. The 2-5% best rocket to the top leaving the rest struggling to some extent.
The hidden problem is the type of traits this artificial natural selection culture says are favorable. Narcissism, solipsism, psychopathy, short-term thinking and avarice have all made their appearance. In other words, according to the culture of our time, having these traits helps our chances of success in life. In contrast, prior cultures would encourage piety, fidelity, chivalry, planning ahead, and bravery.
