The U.S. ruling class tries to have it both ways . . .
"We hold these truths to be self-evident...that whenever any form of Government becomes destructive of [life, liberty, and the pursuit of happiness], it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness. [W]hen a long train of abuses and usurpations...evinces a design to reduce them under absolute despotism, it is their right, it is their duty, to throw off such Government, and to provide new guards for their future security."
--American Declaration of Independence, 1776
"It shall be unlawful for any person with the intent to cause the overthrow or destruction of any government in the U.S., to print, publish, edit, issue, circulate, sell, distribute or publicly display any written or printed matter advocating, advising or teaching the duty, necessity, desirability or propriety of overthrowing or destroying any government in the United States by force or violence."
--U.S. Code, from a 1940 law still in effect
