Good pictures speak themselves. Years back I watched a documentary about lives of ancient Egyptian slaves who built pyramids. In the film they showed archeological sites exposing slaves' dwellings, a mega city not far from monuments. They lived in a maze of streets inside houses without windows. I then wondered, 'are we any different from Egyptian slaves?' Sure we live in better conditions, we have improved health and longevity. But fundamentally the freedom we perceive is an illusion. Great majority of us practically cannot quit our jobs, and we work in jobs we don't necessarily like. We too work for bread. The differences are superficial. We are slaves just like ancient Egyptians.
