Instead, we get kvetching and hand-wringing about "what can be done", and tittering discussions on online message boards, while society decays even further.
On the supply side, even the death penalty can be priced in when the demand is strong. The narcotics business is one of death, not just due to the criminality and the death penalty in some regions, but also due to no labor protections, prevalent drug use among the producers and distributors, and clashes with law enforcement and rival criminal orgs. This has deterred neither the suppliers nor consumers. When even the probability of death isn't a good deterrent, a probability of imprisonment won't work either.
Speaking of death not being a deterrent to lucrative business, the narcotics industry is not an outlier. Industries involving underwater operations like welding, oil rig work, coal mining, logging, high-rise maintenance, stunt performance, mercenary work, experimental aircraft piloting, and similar all exploit death for large profits. It's just capitalism. So a solution to the drugs crisis needs to work within a capitalist world.
plus now you can just blame china for everything. it's super convenient and lucrative!
Doesn't Thailand/Japan etc have even harsher anti-drug laws?
