I believe Chrome does use Keychain on OS X. The problem is people click the "always allow" access button the first time Chrome tries to access an already stored password, they enter their password, and then the user isn't prompted anymore. Your passwords are safe and encrypted...Chrome can just display them when it's open because it has access, as the user instructed.
