Why do Americans not say you're welcome?

Could you elaborate on why it seems that Americans don't often say "you're welcome" in response to expressions of gratitude? Is there a cultural or linguistic reason behind this? Is it more common in other parts of the world to respond with "you're welcome" compared to the US? And if so, what might account for this difference in etiquette? Is there a specific alternative phrase that Americans tend to use more frequently as a response to thanks? Understanding the nuances of social interactions and cultural differences can be fascinating, so I'm curious to hear your insights on this topic.
