Why it is said that traditional culture should be decisively eliminated

I'll give you an example of the best preserved traditional cultures right now. India, the Middle East, Bhutan and other countries. India's traditional culture has led to India has become the odd man out in the eyes of others, and understand India know that the biggest obstacle to India's development is its legacy of those so-called culture, the Middle East needless to say that people directly reject modernization you look at them to see the development of a good one? Bhutan's life happiness index is high, but it's high on the basis of the numbness of the religious fools, you see the difference between it and the ancient times? Let me give you a counter-example: the United States has a history of 200 years, but is it poorly developed? Hollywood blockbusters have taken the world by storm. Culture has to serve people, and why keep a culture that hinders people's development? Traditional Chinese culture was born in an agrarian society where there was still the custom of martyrdom, but what is the modern society now? Why don't you think about why it didn't give birth to science? Why don't you think about how it has hindered the development of our country? Why don't you think about the ancient architecture occupies a large area and consumes a lot of resources, where it has an advantage over modern buildings? (Ancient buildings earthquake that is the rumors of the stakeholders I am engaged in construction), China's modern history so dark and humiliating when the traditional culture played what role? Secondary school for the body of Western learning for the use is not to retain traditional culture is not the result of the Sino-Japanese War well on a lesson. Backward is backward, please do not deny, Japan's Meiji Restoration on the decisive abandonment of traditional culture, so the Meiji Restoration succeeded. The Qing Dynasty wanted to preserve traditional culture, but the foreign affairs movement failed, so there was a great new cultural movement. What can you expect from a culture that can't even protect itself from being lost?
