Both Socialism and Modern Liberalism assert the government can effectively uplift its citizens not only by seizing control of the economy or private institutions, but also by keeping a close watch on citizens to ensure that none of them become subversive.
Furthermore, after doing a little brushing up on political science, from what I read, modern liberalism says that the state should interfere not only in economic or political affairs, but also in social affairs, such as day-to-day activities of its citizens. In effect, modern liberalism ceases to be associated with classical liberalism, and instead becomes similar to socialism.
