> About 90% of reporters are left of center How would one even go about defining what center is? And when we say "left of center," how far to the left are we talking about?
This is an important point. One could argue, and some have, that the center of US political discourse is actually firmly right of center, especially when compared to European nations for example.
the other thing is, in the us, people say “left” a lot which they really mean is “liberal” (which itself is a very blunt word to be sure)
if put in that context, then saying the media is slanted liberal (market oriented, individualistic, capitalist etc) is probably true (at least from a layman’s eyes)
when reframed in that way, there are very few “left” media in the us; it’s either conservative (socially, right-wing) and liberal corporate media
