If the New York Times really believes its columnists primary purpose is to make them money rather than influencing the world, they should follow it through to the logical extension. They need to know which columnists are actually making money for them, which ones people are actually willing to pay for, and jettison the worst revenue earners.
To accomplish this they should allow people to purchase, for a modest fee, an annual subscription to one columnist or to a subset of their columnists. The one who takes in the least revenue should be, every 6 months, rotated off the island. That's capitalism, baby.
