One group "increased incarceration" definitely has a non-marginal positive impact on are all-of-the-above.
Can you show me any examples, anywhere in history, where a group that directly benefits from and controls the entry level and duration of access have ever decided to lower their wages and put at jeopardy their livelihoods?
Because at the heart of it, that's the real effect that decreasing incarceration will have...closing jails, firing police officers, lowering ridiculous attorney fees, and shutting down county court complexes.
And we are surprised when the very people whom benefit from the status quo don't see things the way we do?
