The bigger problem with capitalism is it is designed to perpetuate entrenched interests and status quo. It origins from a time when few had capital or property, only the nobility did, convenient, and was obviously designed to perpetuate feudalism by proxy as they could direct economies and systems with their resources, and continue to.
A few examples of those who sacrifice their entire life to gain more capital offers eternal hope to the masses to hop on to the gravy train some already are on by birth, and those who sacrifice their life to accomplish this are obviously going to be overzealous supporters of 'the system', their entire identity and self worth riding on this achievement.
We need to find a way to detach progress from capitalism. Human progress cannot depend on greed which is basically what capitalism boils down to, rewarding and perpetuating the base traits of humanity and leaving a soulless society unable to rise above basic greed in its wake.
