And American Buddhism is similarly fine if you actually apply the teaching to destroy the illusion of an ego rather than making it stronger.
Buddhism is not a work in progress. Buddhism is a all about preserving the path the Buddha taught, not improving it, changing it in any way. Why? Because Buddha attained full and complete enlightenment, something that doesn't occur that often, and after that he taught us how to attain that realization.
Still it is obvious that Buddhism is so different in Japan, Tibet and Sri Lanka, right? Many different methods that are supposed to make us attain the Buddhas realization seems to have developed. But all these lineages of these methods are similarly very preserving and normally trace the the lineage of their particular method back to the Buddha or an other person that attained enlightenment.
So Buddhism really evolve only on the surface, it will trace even its new methods back to a person actually attaining some kind of realization, as a minimum, or it is considered a degeneration. The wisdom, the realization, the goal is always the same.
