Where do you use math in your profession?
i am a anesthesiologist, when i give anesthsia to my patient, i must know how much medicine my patient needs, and when i should add some, for patient's safty, i must know math first, although i just use simple math in my work, but it's really important to me and my patients, you can't predict what you will do in future, math is a basic skill we should take.I hope your students can know how important the math is.

Everyone can be happily unemployed.
we can't stop the progress of technology development, when we can't adapt the changes of the society, or the world, there will be a revolution which can help us change our mind to adapt to the world and continue to survive in the world. DO something for our worries.

Should public schools in the United States eliminate the traditional A to F grading scale? And if so, what assessment do we replace it with?
i feel very surprise after i reading your conversation, your situation is very common in China, you know, the education is very important in one's life, it's just a way to develop a person, every one accept the same education ,but sometimes the result is different from everyone , maybe several years ago ,you are in the same class ,but several years later, you are in different life , what cause the difference is the real problem we should think about.
