When in the Course of human events it becomes necessary for one people to dissolve the political bands which have connected them with another and to assume among the powers of the earth, the separate and equal station to which the Laws of Nature and of Nature's God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness. — That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, — That whenever any Form of Government becomes destructive of these ends, 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. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn that mankind are more disposed to suffer, while evils are sufferable than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object 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. — Such has been the patient sufferance of these Colonies; and such is now the necessity which constrains them to alter their former Systems of government.

When Ho Chi Minh wrote the US asking for assistance, he quoted that document because it describes what socialists want to protect through structures they control. Everyone deserves life, liberty, and the pursuit of happiness. The Marxist project is understanding the things which deprive people of those rights, what effect it has on those people, and what the alternatives are to achieve them. Not building those structures in a permanent, radical way will only allow them to be undone as the New Deal was while not challenging the injustices because they don't presently affect you is gambling on temporary social prestige when the social fabric will only continue to decay. By that document there is a moral duty to abolish government and institute a new one organised around new principles and new forms to guarantee safety and happiness.
