Really? Math is useless? English is useless? History is useless?
If an educator can't articulate why you are learning something, they are a BAD educator.
Math is useless--until you start trading on Robin Hood and can't calculate the financial implications of turning over your stocks that fast.
English is useless--until you are standing in front of a judge and don't have enough literacy to understand that what got written down on the official paperwork isn't what the judge ruled.
History is useless--until you have a President fomenting an insurrection and you join in because you never studied what happens to 99% of all insurrections.
