Won't happen. Especially if most US citizens are deemed unemployable due to AI taking over most work. Most citizens would be a write-off then.
My future prediction:
Democracy will be ending in the United States. This is because those in power know that most people are not going to be able to be employed in the intermediate to long term future, and the citizens will try to use their voting power to try and reverse this.
Here is the plan of those who are currently running the US government: Slowly strip away constitutional protections, make voting harder, close the supreme court, suspend habeas corpus, throw people in prison on "Trumped" up charges, create an autocratic state.
Now, they are in a position to deal with those pesky unemployed citizens.
They would probably have voluntary euthanasia for a while. They'll start with senior citizens, then work their way down to younger unemployed people. The eventual endgame is mandatory euthanasia after that for anyone who is viewed as a "parasite" on society (i.e. those who are chronically unemployed). Eventually, after most of the citizens are put down, there will be 10 million people left in the united states. Out of these 10 million or so, there may be 10,000 to 100,000 who are living in a life of luxury. These will be the party and inner party members. The rest will be living on a very precarious edge where losing their job will mean being taken away to be euthanized by the secret police immediately after being terminated from employment.
Let's look at what would happen if there is a widespread attempt to overthrow the US government due to the forced euthanasia program:
If the revolutionaries are looking like they are going to win and overthrow the US government, a warning would be broadcasted stating that nuclear weapons are about to be used. If they continued to capture more and more territory, I think all it would take is one nuclear explosion in the revolutionaries center of power to force them to back down.
Sure, guerilla warfare would inevitably result. But the government could threaten to explode another.
The authoritarian government would do anything to stay in power using any means necessary up to and including nuclear civil war.
