Could it be that we taught them capitalism and they just excelled at it. Capitalism is easy if you have everyone giving you what you want for that which you find to be worthless to you but valuable to others whom you have trained.
So capitalism is actually a natural phenomenon...ha ha ha
No it is just put forth that way. Historically we are more appt to share and care for our own.
