Chaplin was not pleased with the widespread popularity of "Solidarity Forever" in the labor movement. Late in his life, after he had become a voice opposing (State) Communists in the labor movement, Chaplin wrote an article, "Why I wrote Solidarity Forever", in which he denounced the "not-so-needy, not-so-worthy, so-called 'industrial unions' spawned by an era of compulsory unionism". He wrote that among Wobblies "there is no one who does not look with a rather jaundiced eye upon the 'success' of 'Solidarity Forever.' "I didn't write 'Solidarity Forever' for ambitious politicians or for job-hungry labor fakirs seeking a ride on the gravy train.… All of us deeply resent seeing a song that was uniquely our own used as a singing commercial for the soft-boiled type of post-Wagner Act industrial unionism that uses million-dollar slush funds to persuade their congressional office boys to do chores for them." He added, "I contend also that when the labor movement ceases to be a Cause and becomes a business, the end product can hardly be called progress."
