Through most of history, monarchies were the original form of totalitarian state. The individual had no power and little chance for upward mobility beyond their class at birth. The Constitution of the USA was a major breakthrough for the ideal of Democracy. It outlined a strategy for how humans could self govern and get beyond monarchies. It also made provisions for the freedoms needed for upward mobility, based on talents and hard work, instead of just birth right.
For one, the Constitution required smaller government. Big Brother was closer to the totalitarian state than was Little Brother. The Founding Fathers saw this and made provisions to spread out power, through the three branches of government, to offer further checks and balances.
The Constitution is still a good litmus test to help us figure out who is pushing for a Totalitarian state, versus who is in favor of a Democratic State. Those who wish to weaken the Constitution, in favor of more government control, do so to make it easier for some form of monarchy to return.
For example, one of the pillars of a free society is free speech. Those who wish to limit free speech, knowingly or unknowingly, shift things back toward how a totalitarian state works. In such a state, all information is controlled, so the people can be fooled by a subset of all useful information. A Ministry of Disinformation, that is led by those who once condoned disinformation, is a tell.
One can tell the totalitarian tree by the types of fruit it bares. The Constitution is a good way to size up fruit, that might look exotic and new, so we can tell the difference, before it takes root.
