A friend just received a $200,000 advance on a book that is about something timely and has a significant celebrity and beautiful-people component to it, and let's just say it's not what one might call serious literature (nor is it meant to be). Another friend commented on how "unfair" that was.
Here's my advice: If you think about the publishing business in terms of fairness, you'll drive yourself to fits of rage. Publishing is a business and, generally speaking, its goal is to profit from the sale of books (and rights and ancillary products, etc...). If a large mainstream publisher has a choice between signing an author with a sexy book that will appeal to enormous numbers of women (we are the ones buying most of the books), or a more artful book with a more narrow appeal, who do you think is getting a book deal?
Now, small and independent publishers often have missions that do not begin with: Make as much money and appeal to the most people as possible.
If your niche-y idea, well-written of course, is rejected by large publishers, that's probably because a large publisher isn't the right place for your book. If you want a huge publishing house to sign you, you have to offer it a huge publishing house-kind of book, including a great platform.
Do yourself a favor and eliminate the word "fair" from your vocabulary. Think instead in terms of matching your work with the right publisher and doing your part to demonstrate you have what it takes to work with that publisher.
