How do you understand how life works and the system ?

Everytime I step outside the house, I'm just observing so much like how certain things work or how people behave and interact with one and another. And I still don't understand the meaning of life and the system it has been setup. Like most people would say the rich only keeps getting richer and hate paying taxes. You have follow a system of rules in functioning society like when you drive. You have to stop at the light otherwise you'll get ticket. At a job, you have to show up on time and do the work otherwise you'll get fired.
