The horse is already out of the barn.
If you create things and expect to get paid, then, brother, this is not a good time to be in the process of making a living. The people who profit from cheap or free content are doing well. The makers of said content aren't. That's as simple as it gets.
Why highlight Philip Roth? He doesn't even write books anymore. You're talking about a dispute between legacy publishers, which is what Hatchette really is, and Amazon. The time to fight Amazon was over a decade ago when they got into the business of undercutting the prices of publishers.
Amazon has thousands of non-mainstream writers who specialize in niche books that make some money (in some cases, more than you imagine for robot porn and things of that nature). They don't care if Roth is upset. They're not paying attention to anything other than how to get content--physical and downloaded products of any kind--into the hands of people. They only care about getting as many people hooked on free stuff as possible, which is why Amazon has Amazon Prime and other ways of getting content for free.
There are more and more books no one wants to read coming out. There are whole albums full of songs no one wants. There are movies no one goes to see. There's almost no way to make a living writing or making music or making visual art anymore. You can get paid making coffee for people and you can get paid stealing content. You can't do much else.
