Some blame the drug companies. I don't. They are corporations. Their managers are ordered by law to make money for the corporation. They push a certain patent policy not because of ideals,but because it is the policy that makes them the most money. And it only makes them the most money because of a certain corruption within our political system-a corruption the drug companies are certainly not responsible for. The corruption is our own politicians' failure of integrity.

As I've indicated, most books go out of print within one year. The same is true of music and film. Commercial culture is sharklike. It must keep moving. And when a creative work falls out of favor with the commercial distributors, the commercial life ends.

This does not mean that every copyright must prove its value initially. That would be a far too cumbersome system of control. But it does mean that every system or category of copyright or patent should prove its worth.

The current term of protection for software is the life of an author plus 70 years, or, if it's work-for-hire, a total of 95 years. This is a bastardization of the Constitution's requirement that copyright be for "limited times."

While the creative works from the 16th century can still be accessed and used by others, the data in some software programs from the 1990s is already inaccessible. Once a company that produces a certain product goes out of business, it has no simple way to uncover how its product encoded data. The code is thus lost, and the software is inaccessible. Knowledge has been destroyed.

By the time Apple's Macintosh operating system finally falls into the public domain, there will be no machine that could possibly run it. The term of copyright for software is effectively unlimited.

Legislation needs a better reason than that lawyers like it, and that America does it.
