Not quite.
It used to be that every town had lots of breweries and beer was more of a local product. Prohibition killed all of that. When it was lifted, we had the ability to mass-market: refrigerated rail cars and delivery trucks were a thing, and so the breweries that survived wanted to market to as many people as possible.
Roughly 10 years later, WWII broke out and a lot of men went to war. The people left to drink beer were women workers: think Rosie Riveter.
So, the big Brewers designed their beers to appeal to women. They all landed on light lagers - clean, crisp, and (imo) mostly flavorless.
American malters grew their crops specifically for this style, American hop growers grew hops for this. The entire domestic beer supply chain narrowed down to produce light lagers.
It's only in the past couple of decades that American beer started to get flavor back, Lee by Boston Beer co, and Sierra Nevada. It's only within the past decade or so that we have seen true innovation and variety.
Anyways, my original point is that your American Macro brew is what it is because it was designed to cater to women.
