You are probably right. For EDM, cultural differences have kept the US lagging behind Europe and the UK. EDM-specific clubs are not common outside of major cities known for nightlife. A lot of EDM tours end up at venues that aren't designed for EDM. These are the conditions informing people's tastes, so probably a big factor for why bass isn't as prominent as elsewhere. There truly are fans an places where it is very much alive, just not as strong as other places IMO.
