The philosophical analysis on the scientific points of the socialist theory of Marxism

Recently, with the economic development of the capitalism, there are many changes in the capitalist societies. Previously, K.Marx and F.Engls think the old capitalist regime was on its last legs, but they are doing well, now. So many people came to suspect the scientific points of socialist theory of the Marxism. What is more, they came to deny the whole Marxism. So, I think it is necessary to analyze the scientific points of the socialist theory of the Marxism. Now, the important problem is how to develop the socialist view of the Marxism. This is the real essence of the socialist view of the Marxism.
