Maybe refine that to "well meaning people Who don't do their homework and cause chaos." I don't get It, we have access to so much good info. And the oldest meme I remember is" to be successful copy a successful person". It's so simple - with drugs copy Portugal. With education copy Finland...with how not to meddle with birthrates consult china, and so It goes on.
