Brainwashing and teaching us to obey authority. I reccomend that anyone that actually cares about their children to home school them and forget about the corrupt schooling system.
It is okay thatvwe have this school system as it teaches us the basic education, but the sad thing is, they don't care about the student's physical and emotional health.To get you ready for your slave career.
This is also another issue. School only focusses on the academics structure but not in the financial aspect. School system does'nt teach students about the need in harnessing their financial literacy. They tend to focus more on a stupid and complex mathematics. Schools are creating employees not entrepreneurs. 
School is supposedly the training wheels for real life. Unfortunately, a lot of them are hexagon shaped and not circles. A lot but not all of them. I suggest you watch Ken Robinson's TED talk about education. It really is inspirational and thought-provoking.
Yeah, thanks for your suggestion.
