why do Americans like a little "kick" in their food?

I always hear this line a lot in YouTube and TV shows etc the United States even though is in the Americas is a predominantly white/European descendent country so as compared to other countries like Germany or even the UK why are there more spicy and extreme spicy options in the States with bottles of hot sauce served in restaurants with a huge usage of dry spiced seasonings in cooking like paprika and cayenne? TIA!!
