I still find it mind-boggling how some people can be so surprised by the fact that people in general act in their own interest. A normal, healthy human being is exclusively concerned by its own well-being and that of its immediate family. T

I see so much arguing over terms and definition, while the basic premises and dynamics of the system should be familiar to everyone. It's a fact that we're witnessing the concentration of capital into the hands of fewer and fewer.
