Which profession will be adding the most value to society in the foreseeable future?
We need knowledge. True knowledge, that recognises its shortcomings, that can immediately throw away yesterday's "truthts" IF proven wrong (by scientific method - Not political or religious whims).
For that we need teachers. Not just any "teachers" but teachers aware of their own weaknesses not shy to recognise them. Able to see potential in students, ready to share and encourage them to explore and find their own talents. Their inner calls. HUmble enough to learn from students as well.
Not something you find often in schools of today.
