What is the Thomas Nast cartoon Harper's Weekly (1878) about?

Caption: Always Killing the Goose that Lays the Golden Eggs. Communistic Statesman (Without Responsibility). "Nothing In It, After All; It's Too Bad Now I thought He Was Just Full of Them."

Source/Date: Harper's Weekly, March 16, 1878

Ultimate Source(if different):

Creator: Thomas Nast

Remarks: This is one of several similar cartoons in response to the great rail strike of 1877. Much as Harper's was willing to denounce the railroad "monopoly," in a strike it always sided with the carriers. However, in many images the magazine suggests that it was the railroad "monopoly" that was leading to labor radicalism.
