Lyric discussion by meandthefrenchexistentialists_ 

I think this song is about a revolution. The first half is the person in power telling citizens that everything is to be feared and their oppressive policies are "protecting" the people, then the second half is the people rising up and using the person in power's words against them.

The first instance of "Be afraid of the lame, they'll inherit your legs/Be afraid of the old, they'll inherit your souls/Be afraid of the cold, they'll inherit your blood/Apres Moi, le deluge/After me comes the flood" is the PIP saying that the people who are different are hurting the nation and then that if they do not stay in power everyone will be destroyed. Then, in the second half, it is those people that the PIP was oppressing who they should really fear, as they are creating a new nation by the people.
