But then I remember that so many are counting on the fact that people will stay uneducated so they can rip them off.
do you think heroin addicts and cigarette smokers never heard that it was bad for them?
For instance, Portugal had a crisis 25 years ago with sky high number of drug related deaths, HIV infections etc. The solution was decriminalization and education, e.g. about sharing syringes. And it worked, they went from the worst I drug related deaths to best. Heroin is still bad for you and I guess people still use drugs, but at least the outcome is not catastrophic anymore.
So yes, I do think education cures a lot of problems.
