Should have kept reading:

But one thing is clear: the 1994 bill interacted with—and reinforced—an existing and highly problematic piece of legislation: The Anti-Drug Abuse Act of 1986, which created huge disparities in sentencing between crack and powder cocaine. Under this bill, a person was sentenced to a five-year minimum sentence for five grams of crack cocaine, but it took 500 grams of powder cocaine to trigger the same sentence. Because crack is a cheaper alternative to powder cocaine, it is more prominent in low-income neighborhoods. These neighborhoods are more likely to be predominately Black and in urban areas that can be overpoliced more easily than suburban or rural areas. While the Fair Sentencing Act of 2010, enacted under the Obama-Biden administration, reduced the crack/powder cocaine disparity from 100:1 to 18:1, the damage had been done, and its effects continue to this day.

Do you see how this demonstrates the Ratchet Effect yet? Conservatives (and Joe Biden) pass a piece of legislation during the Reagan years that causes mass incarceration of black men. Clinton doesn’t move us back to the left, but passes legislation that reinforces the conservative legislation. The closest the Democrats get to, “turning the dial to the left,” is when Obama gets legislation passed that makes the problem 18 times worse for the black community instead of 100 times worse for the black community, and only after the bulk of the damage is already done. Do you see how even, even when the Democrats, “move us to the left,” things are still worse than where they started? That’s the Ratchet Effect.
