About to reveal what helps Americans get to the top (8)
I believe the answer is:
elevator
'what helps americans get to the top' is the definition.
I can't judge whether this defines the answer.
'about to reveal' is the wordplay.
'about' is an anagram indicator.
'to'+'reveal'='toreveal'
'toreveal' with letters rearranged gives 'ELEVATOR'.
Can you help me to learn more?
(Other definitions for elevator that I've seen before include "Cage that is raised and lowered mechanically in a vertical shaft" , "part of tail muscle" , "it's uplifting" , "what makes flight unnecessary" , "A lift in America" .)
