"This bill has was fundamental to the expansion of the carceral and surveillance state."
Practically a milestone.
The 1990s was a "counter-revolution" in some senses from the civil rights era.
Clinton was Reaganism on steroids. At least, we had the anti-apartheid movement in the United States which culiminated in Congress passing sanctions on apartheid South Africa (back in 1986). Compare that with the next decade, the 1990s, and you begin to see that while neoliberalism may have been introduced 40 or 50 years ago, it doesn't really gain a foothold like it did during the 1990s. And that included the mass expansion of prison labor and a type of neo-slavery. The 1990s are the beginning of that.
(Not that prison slavery wasn't present before, but I think it's good to mark milestones and when things are an "escalation" of some sort.)
