"Bulls on Parade" addresses the American military-industrial complex, a situation in which industry (the arms industry, primarily) urges government to take military action, with the intent of obtaining military contracts, to thereby increase its revenue. The idiom "bulls on parade" refers to a bull market. The symbol may also mean the muscularity of American responses to complex problems; we act like mad bulls on dress parade rather than negotiating or using less violent strategies. Also the verse, "They rally around the family, with a pocket full of shells" could refer to the composer's belief that American politicians in both parties represent the family as an integral part of their policies, but in actuality they use this as a "scarecrow" tactic because they really have pockets full of ammo ("shells") catering to the military-industrial complex.
