If you talk to your parents, wether you are 40 or 15, you may find that they learned the same material in their day as the current generations are learning now, which is not good for a progressive world. Many students are either not exposed to jobs of the future or just don't have the tools to be prepare for jobs of the future.
Much of our school curriculum does not focus on preparing students for jobs of the future, which is based around coding languages. There is a large demand for computer programmers, many jobs involving computers demand knowing at least one computer language, and that seems to not be a priority for our school system.
In conclusion, our current curriculum is just not preparing students for jobs of the future, which limits our country's potential in a big way.
