Because 'Blood, Sweat and Tears Factory' Would Have Been Too Long
Promotional video of the Fiesta Love Factory features people in various states of G-rated ecstasy. Those warm fuzzies are then conveyed out of their bodies and into a Ford Fiesta.
News flash: Coke's Happiness Factory managed to sneak by us, mostly on Coke's frothy reputation and the romance of Willy Wonka, but there is nothing romantic about an auto factory. (Or any factory, actually. I went to the Jelly Belly and saw sadness calcifying behind the taffy machines.)
And lest we forget, Ford was the first home of the assembly line -- which is cool considering it kicked off our industrial revolution and all, but those first assembly line vehicles weren't made with vicarious bliss. They were made on the backs of tired, underpaid mummies and daddies. Think about that next time Papa comes home and demands his nightly gin.
