Hahaa
No. For several reasons. First off, it wouldn't be a revolution it would be a civil war.
Secondly, you seem to have highlighted economics as the reason for this war, in which case, hells no. America's attitude towards its poor people seems at least to an outside perspective to be, clearly these people were not good or motivated enough to make themselves rich. The American dream is still that of the self made man and almost every facet of American society reflects this. You don't give relatively as much to charity as every other nation on earth, you don't think that poor people should be given health care or housing or in fact any aid at all, and any policy which comes the slightest bit close to 'help people with less money than you' gets immediately shot down as being socialist, I have never seen a country as diammetrically opposed to the concept of helping people who need help as America. If the poor ever did start a revolution all the rich would join in the peasant murdering, fuck it'd be like Medieval Europe all over again. (This paragraph intended mostly facetiously but seriously, America hates poor people more than anyone else I know)
Which brings me to my next, less ridiculous, point. The American Military. I know the Second Amendment is supposed to be this great equaliser and it means that 'the people' can stand up to 'the man.' But come on, be serious. They have assault rifles, you have handguns, they have a minimum six months training, you have accumulated drunken evenings shooting bottles off your fence, they have tactics, strategy, huge military computers, the combined efforts of the police, the secret services, the navy, the military, the air force, you have can-do spirit and a little grass roots thing going on. They'd steamroller everyone. This isn't the 1860s where every is as well armed and trained as the army themselves, the gulf between trained personnel and the layman is so great in America that you'd be lucky to even kill one soldier before the revolution was over. The Second Amendment's supposed original purpose has about as much relevance nowadays as the Seventh. Unless the military joined you but come on, why would they ever join a socialist grass roots revolution?
So there's two extremely good reasons. I do have more.
. But nevertheless, I believe you wrong for saying America hates poor people. I have come to the conclusion that we dislike them but if a documentary covering the homeless comes out, we will help them.
