"FOR A YOUNG WRITER who hopes to produce literature, the greatest difference between now and twenty years ago may be that now she expects to get paid. Twenty years ago, art and commerce appeared to be opposing forces. The more you were paid for your work, the more likely you were to be a hack."

Being a… tad… older than twenty years this is just nonsense. Unless you redefine any successful author — or author that receives payment — as, by definition, not writing literature.
