I agree with just about all of what you said. So many bad things are tied to this. Crime rate. Horrible educational results and environments (I worked in Baltimore schools as a contractor and it's one of the saddest experiences I ever had and I'm a combat vet).
One thing to remember though about the war on drugs and especially the opiate crisis is that it was also largely a creation of the CIA who learned it from the Brits who had been doing it as far back as the opium wars. Black markets provide black money budgets not overseen by Congress, and the CIA really hates oversight (they prefer overlook committees). The main opiate crisis in particular stems from Vietnam, where generals would play along for a cut while the CIA had drug operations all over including Laos, etc. They'd then ship it back and sell it specifically in the inner (mostly black and other minority) city.
The same thing is true of this opiate crisis. The war in Afghanistan has massively increased poppy production (which the taliban had outlawed) while US forces would eradicate weed crops they allowed poppy fields, and low and behold, the vast majority of the heroin, etc now in America can be traced (Chem analysis) right back to Afghanistan. I promise you it's Vietnam on repeat, and the CIA has their hands all over it.
Of course south America is the same. Behind every top cartel member is a CIA man pulling their strings, and look at the destruction they are wreaking on the border towns. The death toll of civilians is higher than allied casualties in OIF!
It's just like Iran contra. Since lots of the time they don't want to pay full price, the Intel agencies will ship arms to them as well.
It's high time for a new church committee!
The problem is the surveillance engine is so pervasive, which enables the blackmail and extortion system, just about every senator or congressman who pushed back would be quickly compromised.
This is the real deep state, in the Peter Dale Scott sense of the term, and it must be addressed if we are going to strike at the root of many of our problems, instead of hacking at the branches.
