@Novichok, we learn about history of humankind in order not to be morons. History is not only about ancient times, but also about what happened in the 20th century, for example. The rise of communism, facism, Nazism, World War I, The Great Depression, World War II, women's emancipation, the Cold War, the fall of communism, etc. etc. History helps us to understand the present day reality, to learn from the mistakes of the past, it makes us more conscious voters.
I said that 90% of "education" is useless crap nobody ever needs after graduation.
I disagree. Someone may not need math after graduation, but someone else may need it. Kids don't know what they'll end up doing in the future, they often don't even know what college they'll choose. Education at school helps kids to see what they're good at, what they find interesting and thus it helps them to make decisions about their future.
Another example...I "studied" Russian for 7 long years. After graduation, I wouldn't know how to ask for directions
That means you had crappy teachers or you were a lazy student. I certainly knew how to ask for directions in English after graduation lol
I'm not saying that education is perfect, including in Poland - I'd change some stuff myself. But in my opinion your conviction that '90% of "education" is useless crap nobody ever needs after graduation' isn't correct.
