1. Different class bases: the fundamental starting point and ultimate goal of bourgeois political parties are to safeguard the interests of capitalists and capitalist systems, while the people's position is the fundamental political position of proletarian political parties.

2. Different value orientations: the slogan of serving the people advertised by bourgeois political parties is hypocritical, and its so-called service is essentially seeking to maintain and consolidate its ruling position, while proletarian political parties always regard the fundamental interests of the overwhelming majority of the people as their highest interests and effectively protect people's basic rights and freedoms.
