The U.S. Constitution is not very complex. It was designed to "chain down" government.
After all, government is the most violent and vicious institution on the planet. Most people have to keep learning that the hard way.
The natural tendency of government is to constantly expand its scope. It wants no limitations on the violence that it inflicts, and it surely doesn't want to be "chained down" by anyone or anything.
All politicians in the United States swear to uphold the Constitution. Bibles are used ... big hyperbolic speeches ... marching bands ... the whole nine yards.
Yet, immediately after the pomp and circumstance of the "swearing in," the U.S. Constitution is almost completely ignored. A vast majority of everything the federal government does is purely unconstitutional.
