I think it's a degree of laziness/marketability in Hollywood...
I used to work in a record store and sometimes people would bring back subtitled films because they didn't want to "read a film" - seriously, there
was at least one incident of this a day and that was people that accidentally picked them up, there were a lot of others that would actively avoid
subtitled films.
I think Hollywood avoids producing subtitled works for that very reason, that a lot of people won't see something with subtitles...
Also "actors" are perhaps not as dedicated to their art these days and won't go to the trouble of learning a realistic accent.
Personally I have no trouble with subtitled material, but I find someone doing a poor imitation of an accent very off-putting and would rather have an
actor just perform in their normal accent rather than make a pigs ear of it.
