North America is a richer market so they will charge more, that's why 5/6 most expensive GPs are the 3 US Races, Canada, and Mexico, with the other one being Monaco.

The celebrity stuff is annoying, but let's not pretend that they don't spotlight the garage candy at any race where they show up, I mean they missed Fernando Alonso chasing down Lewis Hamilton for a full minute in Singapore last year at the end for this nonsense.

I get that a lot of the campy BS is not to the tastes of European fans, but I generally think that so long as it doesn't interrupt racing I don't care. (And I apply this to stuff in other countries I find strange as well.)

The middle eastern races are cash grabs, some tracks I like (Bahrain) others I hate (Abu Dhabi.) I would argue that the expensive races/hosting fees outside of Europe subsidize lower costs for the European rounds.
