One point of the drug crisis is that it's people with money who are the target customers. The percentage who become homeless drop-outs are the fallout, they're not the target market. It's like pointing out dying alcoholics as the target market for alcohol and saying that's the whole alcohol market. It's really not even the smallest segment, and it's certainly not the business plan of the alcohol companies to turn everyone into homeless derelicts who are dying of cirrhosis. The actual median drug user has a good job so they can pour a ton of money into it. Relying on scabby people who break into cars so they can afford to buy the drugs isn't a reliable business model for a dealer network. You get people turning up trying to barter a car radio for drugs directly, that's the sort of shit dealers actually have to deal with daily with those types. It's like if someone came into your shop trying to barter live chickens for stuff, that's how that feels: "what they fuck am I meant to do with these car radios?" My pot dealer even have people trade him food bank vouchers for drugs, now, that shit doesn't fly with suppliers, you only accept those if you feel sorry for the person, so he had no pot, no money and a ton of food bank vouchers he didn't need.
There's a reason the direction of the drugs is into the richest country in the world from poor countries and not the other way around, and that's because the real target is the wealth. Hence it's logical that they're not really after the handful of bucks that homeless people have access to. An example of how the dominant mindset is wrong is how in Florida they drug tested tons of welfare recipients to kick them off the payments if they tested positive for drugs, and the cost of running the drug tests actually exceeded the money they saved from people they kicked off the system. no shit. Poor people aren't the target demographic, no matter what you're selling.
So yeah, "clean up the junkies" isn't really solving the problem, those are just collateral damage of the middle class' huge drug consumption. They'll target the poor and most obvious addicts while never doing anything that might upset the powerful apple carts that keep rolling along. Some very powerful people are working with these drug cartels, and their target clients are people with significant disposable income and nothing else to do with it, not some skanky street junkies, which is why periodically clearing out homeless drug addicts and the like never works for very long. They're are a handful of really skanky junkies in a lot of small towns, but those visible guys aren't really numerous enough nor reliable enough to maintain a profitable supply network, are they?
