(1) Everything develops and changes, and people should make adjustments according to the development and changes of things. The same is true of governing the country. Any social system is the product of the economic base at that time. With the development of productive forces and the change of economic base, the social system must also change accordingly. (the answer is reasonable)

(2) It shows the strength of conservative forces. The new things that represent the future development direction are weak at first, and will inevitably be opposed by the old things everywhere. Therefore, its development cannot be smooth sailing. Any social change will inevitably touch the interests of some people, especially when it touches the interests of those in power and those in power, it is even more difficult to change. Therefore, we should not only be full of confidence in the social changes that conform to the historical development trend, but also be prepared for setbacks. (the answer is reasonable)
