It based on comparative studies between the capitalism and post-capitalism in perspective of political, economic, culture, and society. As we all know post-capitalism comes after capitalism, but few point out the difference between them, which encourage me in this article to point out the essence of post-capitalism. Post-capitalism based on new technology of communication arid social organization. which challenged different aspect of life and human relationship. Computer changed the value of behavior on daily life, new individualism take place of the old individualism, consumer economy become the new trend of public opinion, emotion getting more important than reason to deal with problems.

I divided it into five parts, from what is culture through capitalism to post-capitalism to let the audience understand what is world we live with.
