No, it is actually one of the slowest spreading ridge on Earth. The slowest ridge is the Southwest Indian ridge, while the East Pacific Rise is the fastest.
The Pacific Ocean is shrinking as the Atlanic Ocean is spreading. Subduction is occurring in the Pacific ocean and the continental plates are moving and that changes the placement of the oceans.

Divergent Plate Boundary. (Seafloor Spreading).
Because the subduction of the Pacific Plate is very near to centres of human population at the edge of a continental plate, whereas the seafloor spreading in the Atlantic is in the middle of the ocean, far away from human habitation.
The Pacific seafloor formed at a faster spreading rate than the Atlantic seafloor.
America did not spread the Pacific. The ocean was there long before America existed and it has been about the same size for millions of years.
actually no, it is getting smaller as the Atlantic ocean gets bigger due to the contininents of Africa and Europe being pushed further away from the Americas by the mid Atlantic ridge. But as you observe the official data on ocean floor age, you might come to another conclusion.
