A bit of interesting off-topic : I think its a disservice to general knowledge propagation to use personification when taking about systems. People can care, biology and systems in general cannot, they simply have consequences. I blame Richard Dawkins for this (and his very badly titled Selfish Gene)
Caring is part of the system. It is an aspect of the system that only exists because of the system itself. To refuse to analyze this is basically lying to yourself. EVERYTHING is a system.
