Does Global Entry work for travelers or for the government?

Does Global Entry work? Here’s what the government doesn’t want you to know

When the federal government proposed a trusted traveler system years ago, I got into an argument with a well-known travel writer.

He claimed a program like Global Entry that subjected you to a background check and stored your biometric data would never work. He argued that the government had no interest in collecting that information and keeping close tabs on its citizens.
