I have nothing against learning anything and encourage learning to learn. But my biggest issue with the education system as a whole (even in Canada) that it didn't caught on with the times we're currently in and is far from efficient than I would've liked.
The worst offenders of the still ongoing problematic are the secondary schools. Primary schools already gave children enough time to cover every subject that secondary school mostly does, albeit with the basics that everyone needed to know in order to choose their future career. Even the essential classes exclusives from secondary schools might as well be in primary schools, along with a more integral language learning thrown to the mix.
The secondary school by design mostly serve to waste everyone's time and money for at least 5 years with pretty much every information that can be easily found by searching in the Internet on their spare time. Instead of going to the secondary school, they should skip straight to the cegep/college to learn their specific topics of their choice, so they can finally have their best job with a fairly healthy wage at 16 years old, rather than 19+. Which also brings us to...
...the fact that everyone learns at different pace no matter how the currently aged education system forces them to. Some of them can learn pretty fast and become bothered by the school's not being quick enough for them, while others take a longer while to digest the same thing as the faster ones can.
Some classes are also completely useless by their nature whenever attempted to be learned by students on schools and colleges. You thought math was useless? Well, any class that involves history of all sort is among the most prominent example, since every single information can Googled anytime, anywhere. Otherwise, it's all about memorizing facts and regurgitating.
The education system is still useful today even with its flagrant flaws, as parents might not have enough time to raise their children to learn things they needed to learn. But, we're now constantly wishing the government will actually overhaul the entire outdated education system for suiting the needs that we're experiencing today, so everything would go smooth sailing. Even though the Canadian educational system is a bit better than the USA one in general, we're still missing some of the basic of the life that could be learned before we hit on our teenager years. The entire school debacle sure is worth doing waves after waves of strikes just so the government get the job done!
