I would substitute "literature" for "literary fiction" in the title of this short article by Elizabeth Kaye Cook and Melanie Jennings from Persuasion, but a lot of what is says about the state of publishing in the 21st century is spot on. Witness:
Mirroring many other American industries, publishing has followed the path of consolidation, starting when Random House bought Knopf in 1960. What followed was a fifty-year feeding frenzy of mergers and acquisitions. In 2012, when Random House and Penguin merged, we were left with today’s “Big Five”: Penguin Random House, Hachette, Macmillan, HarperCollins, and Simon & Schuster.
And I'm not sure I see much hope in the current situation--certainly not for the writers who expect to be paid for their work. Small presses may be good for getting publication, but the terms are unpropitious.
