You can even look back just to the 1900's and the beer styles in America fell into a pretty narrow range - mostly light lagers and light pale ales.
Really?!?!?! Not the America who's beer history I have read about.
Again, that's sort of a cultural relativisitic bias that the past is somehow "inferior" to the present.
America like most of the world had quite an extensive array of beers available prior to the German Invasion of brewer's which
later introduced the light lager. They pretty much had the "brewing culture" of all the countries that people immigrated from...Most English beer styles..you know Porters, Stouts, Partigyles, stuff like that. As well as mostly heavy German Styles of beer. Not to mention people from Scotland, Ireland, Russia and other places where beer was drank.
Remember up until then,
beer was food.
In fact thew whole history of the light lager is the American
populace's (not the brewer's) desire to have a lighter beer to drink, which forced the German brewers to look at adding adjuncts like corn and rice...not as the popular homebrewer's myth has been to make money by peddling and "inferior commercial product" by adding adjuncts,
but in order to come up with a style of beer that the American people wanted.
Maureen Ogle proved that in
Ambitious Brew it actually made the cost of a bottle of Budweiser cost around 17.00/bottle in today's dollars.
When AH released Budweiser with it's corn and rice adjuncts in the 1860's it was the most expensive beer out there; a single bottle retailed for $1.00 (what would equal in today's Dollars for $17.00) this was quite difference when a schooner of beer usually cost a nickel.
The American populace ate it up!
It wasn't done to save money, it was done because heavy beers (both english style Ales and the heavier Bavarian malty beers) were not being drunk by American consumers any more. Beer initally was seen around the world as food (some even called it liquid bread), but since America, even in the 1800's was a prosperous nation compared to the rest of the world, and americans ate meat with nearly every meal, heavy beers had fallen out of favor...
And American Barley just made for heavy, hazy beer
Bush and other German Brewers started looking at other styles of Beers, and came upon Karl Balling and Anton Schwartz's work at the Prague Polytechnic Institute with the Brewers in Bohemia who when faced with a grain shortage started using adjuncts, which produced the pils which was light, sparkly and fruity tasting...just the thing for American tastebuds.
So the brewers brought Schwartz to America where he went to work for American Brewer Magazine writing articles and technical monographs, teaching American brewers how to use Rice and Corn...
The sad moral of the story is....The big corporate brewers did not foist tasteless adjunct laced fizzy water on us, like the popular mythology all of us beersnobs like to take to bed with us to feel all warm and elitist....it was done because our American ancestors wanted it.

So again I wouldn't go saying that American's choices were limited to Light lagers and Light ales.....They really had everything that was available to any sea faring culture, especially the culture and styles of the countries they came from.
