Marge vs. the Monorail employs an association fallacy to attack and discredit monorail technology.
Conman Lyle Lanely (think "Professor" Harold Hill from The Music Man) proposes and installs a monorail for Springfield. However, he embezzles money and delivers an improperly designed and improperly built monorail system. The show goes on to show what a disaster the monrail is, and closes with Marge reflecting on how monorail is "folly".
The only folly here is of the Simpsons' selling its viewers a sham; discrediting a technology because someone used it incorrectly.
Have honest, competent engineers build a monorail system for any city and it will be a huge success.
Articles using "Marge vs. the Monorail" to dismiss monorail technology:
In a world where economies loose billions each year due to traffic congestion, and in a world rapidly warming due to human consumption of fossil fuels, and in a world which looses millions of acres of wilderness to sprawling development and road construction, we need more green, electric, automated, elevated transportation systems such as monorail, and they need to be represented fairly on television and in the media. This is a commitment to America’s future.
The first city to do monorail correctly will be the envy of the world.
