My essay's title references the title of Dinesh D'Souza's 2014 political-philosophy book AMERICA: IMAGINE A WORLD WITHOUT HER, but the resemblance goes deeper than that.

In this book D'Souza, who immigrated from India to the U.S. in his youth, seeks to articulate a reasoned argument in support of American exceptionalism. Rather than depending upon self-aggrandizing patriotic bromides-- "we're freer than anyone else," "we're more generous than anyone else"-- D'Souza follows the historian Alexis de Toqueville in finding America's uniqueness in its entrepreneurial spirit. In D'Souza's view, all the nations of the Earth-- including the native tribes who originally occupied the territories of "The New World"-- were governed principally by an "ethic of conquest." The strongest tribe or nation prospered by non-consensual force of arms, and the winners not only wrote the history, they often considered their victories a mark of divine favor. America, however, was the only nation of the New World to fully invest in the entrepreneurial spirit.
...entrepreneurs created demand by introducing a product that no one asked for, but millions of people wanted once it was available. I call this "extreme empathy" because it's a case of entrepreneurs providing for the wants of consumers before consumers even know what they want. -- Chapter 10.
What D'Souza proposes as the antithesis to the ethic of conquest might best be termed an "ethic of commerce," though D'Souza does not advance this term. The commerce-ethic serves the self-interest of the entrepreneur as much the ethic of conquest serves that of the conqueror. However, the entrepreneur can only prosper by empathetically anticipating the wants of customers, and by persuading them to give him their business, consensually.
One may cavil at this or that aspect of D'Souza's thesis, but I believe he's on solid ground with regard to the element that sets the United States apart from other nations. Fundamentally the country's foremost virtue lay in being founded either by merchants or immigrants who wanted to become merchants, leading to an emphasis upon consensus over conquest. And that leads me to the man who saved the medium of comic books with his relentless promotion of his company's unique products.
Imagine a world where Stan Lee quits the company founded by his cousin-by-marriage Martin Goodman and never brings together a diverse of writers and artists-- some great, some mediocre-- to form the Marvel Universe. Lee himself might have faded into obscurity-- but the comics-medium might have followed him within another 10-15 years.

Some things would have remained the same, without Marvel. The "DC Big Three" who had survived the Golden Age-- Superman, Batman, and Wonder Woman-- would have stayed the course. Yet by the late 1950s, DC Comics, the premiere publisher of funnybooks, would still have had mediocre sales on their westerns and SF-books, and the editors still would have sought to goose sales by launching new versions of the company's 1940s superheroes. So The Flash, Green Lantern, and the Justice League would have appeared in that world just as they did in this one. The new heroes, juxtaposed against the staid "Big Three," would have still galvanized the nascent comic-book fandom. And one of the defining events of the sixties, the 1966 BATMAN teleseries, still would have driven the nation temporarily Bat-mad for a couple of years.

Various publishers would still have jumped on the superhero bandwagon in that same period. But Martin Goodman might not have been one of them. Without Stan Lee to run the funnybooks on a shoestring budget, the publisher probably would have shuttered his comics division to concentrate on his line of "sweat mags."

Yet without Marvel, DC probably would have stayed locked in the creative attitudes of the 1950s. A few of DC's more oddball creations might have still appeared, such as Robert Kanigher's METAL MEN. But without FANTASTIC FOUR shaking things up, does any DC editor okay DOOM PATROL? Carmine Infantino might still have ascended to the position of editorial director in 1967, and he might have suggested that DC invest more heavily in horror in case the superheroes flamed out, just as they had at the end of the 1940s. Yet without Marvel as competition, maybe Infantino gets overruled by the people who liked to play things safe. And so the fans don't get Gothic Batman or SWAMP THING, much less the later "British Invasion" of US comics.

Worse, in a comics-world where the dominant creative voices would have been Gardner Fox and Robert Kanigher, comics would have remained rather dull, and so comics fandom might have foundered. Everyone loves a battle between opponents of equal stature, and if all the other history stays the same, none of DC's other 1960s competitors had a chance in hell. Charlton, Tower Action, imprints like Mighty Comics and Harvey Thrillers-- they all had to terminate their superhero lines within a few years. Warren Magazines introduced a smattering of heroes in their black-and-white publications, but that company's base was horror, and arguably they profited only because most of the other companies avoided the genre. In our world generations of comics fans took pleasure in the combative question "Marvel or DC?" and that was because the healthy competition forced entrepreneurs in both bailiwicks to exert themselves, trying to anticipate what comics fans would buy.
Without that crucial competitive spirit, are there enough enthusiastic fans to support a Direct Market in its 1970s infancy? If the DM turns belly-up in its early years, that puts all surviving comics-companies at the tender mercies of traditional distributors. And so maybe by the 1980s, DC is the Last Comics-Company in the U.S., eking out an existence publishing Superman reprint books.

Fortunately, in our world Stan Lee did not quit. Taking at face value his statements on the origins of the Marvel superhero line, it's obvious that he had no thought of becoming the nemesis of the monolithic DC comics. He was bored with his job and wanted to have some fun with the superhero genre that he'd enjoyed as a young man. He may have not expected that the titles he launched with raconteurs like Jack Kirby, Steve Ditko and Larry Lieber would outlast the decade, and indeed, characters like Ant-Man and the Hulk initially did not set the comics-reading world on fire. But Lee was not just a "pitchman" as so many ignorant fans have claimed. He was a creative entrepreneur, and the Hulk eventually did catch fire because Lee kept sending the model back to the shop for improvements. Lee and his collaborators broadly followed DC's example of reviving old heroes. But because they had a different approach to costumed heroes-- an approach that would never have been realized except under the aegis of a creative managing editor-- they formed a mythology that ran counter to DC's. That approach eventually convinced all comics-readers that a world without Marvel Comics was all but unimaginable.
As to what made the approach seem new and different-- see Part 2.
