Knowing some amount of physics, chemistry, and the like come in handy on a regular basis for me in my everyday life. Plus, as noted, knowing how to use the scientific method (how to analyze, hypothesize, and test ideas) is incredibly useful.

I would also argue that economics (home in particular, but also micro and macro), social studies (government in particular, but also other societies), and history all have their places in life and are worth being part of the curriculum. But, aside from maybe home economics, they aren't as useful in everyday life as the STEM topics.

At least, that's my opinion based on my experiences. I only have me to base my opinion on, and I'm a sample size of 1.
