Education is all about indoctrination, we are indoctrinated from birth by parents, teachers, media and anything else that is an influence in our life's. It's only when you get older after experiencing many things for yourself that you can start questioning things and using your brain to think through for oneself which most of the time comes from experience. Use your brain rather than a textbook or what someone else has told you. This is why teachers should be older and have had some experience. Elders or the wise ones as they used to be known as are supposed to be the teachers. Handing down the knowledge. The clue is in the word 'down' as you need to get 'up' first. You can't have kids teaching kids.
Many teachers today can't even read and write properly and most likely use Mr google to write up lesson plans. Mr google is not well educated and makes many mistakes because he listens to everyone instead of only the wise ones with real knowledge. Society as a whole has been gradually dumbed down through the education system and the media. An A level years ago is the equivalent of what a GCSE is today and quite possibly on par with some lessor University degrees today. A degree years ago would wipe the floor with a degree today. There's no comparison. Standards have dropped drastically over the years. Our education system is getting more and more like the US system everyday and they are as thick as shit, half of them think the world is flat and the other half are more concerned about what Kim Kardashian is doing. It's run more like a business than an education system.
