It seems crazy that we've made it this far as a species without medication; so why should it be required now? Maybe the issue isn't the children, but the environment they are in?
- teachers had a lot more options when it came to disciplining kids
- many left school for work at age 15 - 16
Do you want the good old times back?
(Another thing is many countries have changed the curriculum to be even more heavy on theory than it used to be. That I would like to change, both for the kids and for future employers: broad practical experience probably increases someones chances in engineering and probably other disciplines as well.)
