I frankly don’t know why the US government has through several administrations put up with the Chinese government’s tolerance—even encouragement—of massive counterfeiting of intellectual property. They steal software, music, movies, books (there actually was a Chinese Harry Potter counterfeit), and yes, golf equipment.
An article in GolfWorld puts the value of the counterfeit golf products at $240 million or so, but the actual cost is more. Companies suffer from damaged reputations, and have to expend piles of cash protecting their name.
Legitimate sellers also take a hit on these. When counterfeiting becomes prevalent enough, the second hand market will entirely come under suspicion and dry up.
If the problem were just in golf, I might be able to understand why the US government chooses to ignore it. But every industry has been hit by these (primarily Chinese) criminals. And the economic damage is probably incalculable. Someone in Washington needs to develop a backbone and start standing up against the Chinese for US companies and citizens.
