Some believe that what's common is what's natural is what's right. Maybe it's a psychological safeguard system of human mind, if something stayed for a time long enough, nobody questions whether it's right or wrong. That's what happened to all those people who has put up with the system and never thought of fighting back or even taking some changes.
When I was talking to one of my friends about the constraints perpetuated by system, she said: "Freedom is relative". I immediately recognized that it's a sentence taking directly from Marxism doctrine, maybe from middle school Politics textbooks. She is saying the sentence to defend her compliance with the system for we were discussing the time wasted if I joined the party and have to take meetings and writing reports all the time for a Party member status. Her logic is that since we are never in pure freedom, freedom is not worth striving for. I paused to reply. And then I replied with a laugh. It was at that time I realized that we both agree we are constantly living in constraints. And she agrees that we are all jumping from small cages to larger cages. The only difference between us is that she regard what is as what ought to be, and thus freedom is given or taken by the system only, and you need to comply with the system to get more "freedom", e.g. by complying to the party rules or school regularities, one may able to enjoy the member status or get a diploma, with those things, one can ask for more "freedom" from the system. However, I believe we only get the freedom that we deserve, and freedom is not given by the system, nor by selling your present freedom, you could buy more freedom in the future. Freedom is what one strives for, by challenging the system, by breaking the rules, by overriding the context. Took the black people in the States for example, if everyone only saw what they saw, and nobody challenges the existing practices, Obama would never be elected as president. Many Americans have experienced the change during their lifetime. In a personal level, freedom is also what one strive for at the moment. By identifying the constraints of reality, one could create a freer future by challenging them.
I skipped most of the classes in college, refused to take part in any activities related to politics and the Party, absented from most of the meetings, and ignored most senseless calls by the authorities. But when I graduated, I feel freer and happier than others who have complied. I feel my life is not wasted. And because I have taken my time more seriously and learned more things by myself, I actually enjoy more freedom to choose in career than others. And I want continue doing that. It feels great.
