When you are vey wealthy and having a failed business, you use it as a write off. If the NY Slimes just reported just the facts and left out the commentators opinions(they are not articles, they are left wing opinion pieces), then maybe the readership will go up and they will begin to make money.
Wow, what a concept. Telling the truth and gettig paid for it.
