"Most Americans do a certain amount of squawking about taxes. They would probably yell even louder if they realized that (1) the only source of taxes is people, and (2) the individual taxpayer is really paying much more for government than he thinks he is. Like an iceberg, a big chunk of the taxes people pay is below the surface, out of sight. But this hidden tax can be hauled into view with a little hard work."
