I would say pretty much all of the above.
The war on drugs is a revised form of Jim Crow laws, from
The New Jim Crow -
"In the book Alexander deals primarily with the issue of the
current mass levels of incarceration in the United States (with 5% of the world's population, the U.S. incarcerates 25% of the world's prisoners)
[8] and what she perceives as societal repression of
African-American men and, to a lesser degree,
Latino men.....Alexander claims the U.S.
criminal justice system uses the “
War on Drugs” as a primary tool for enforcing traditional, as well as new, modes of discrimination and repression.

Think about it - 5% of the world's population, yet 25% of the prison population, and that includes third world countries. We have close to
7 times the number of people in prison per capita as Canada. That is $60 billion dollars a year not being spent on more future oriented investments like health insurance for all, rehab programs, schools and job training.
