The existence of bad doesn't mean the absence of good. There's next to no good American media produced in the last decade. Maybe even longer. Counter that to a country that regularly produces new, original, captivating stories on a regular basis.
Otherwise unknown artists can and often do make a name for themselves by telling a good story, and their story gets boosted by a functioning entertainment industry.
Contrast that to America's entertainment industry. A filthy and incestuous cabal of people decide what does and doesn't make it. Ideological zealotry required to step foot at the gates. Serial rapists as the gatekeepers using their power to take advantage of others.
