STEM is important, vitally important.
We absolutely need basic comprehension of math and science literacy to be more widespread here in America (and throughout the rest of the world, of course). We’ve seen precisely how dangerous ignorance of those topics can be.
Just as important, we really need accurate, unbiased, objective lessons in history and sociology to be treated as being of paramount importance for our children. The study of history and of social structures is no less imperative than the study of STEM subjects.
Additionally, it would be great if we could incorporate some low level critical thinking and logic education as early as elementary school as well. Mindfulness and self-awareness could be useful too.
Sure, these things wouldn’t lead to a perfect society…such a thing can’t likely exist…but it would make for a better society, more well-equipped to tackle the obstacles that come with both day-to-day life and more challenging times.
