The con is it&#x27;s very difficult to get a government to lower taxes, not so difficult to have them increase it. Also that thing P.J. O&#x27;rourke said: giving money and power to politicians is like giving whiskey and car keys to teenage boys.<p>I&#x27;m not aware of having met anyone who has ever said &quot;I want to pay more tax&quot;, but I&#x27;ve met plenty of people who have said &quot;that other group of people should pay more tax&quot;.
