I agree it's inefficient for everybody to learn advanced science; but basic science? Gravity for Newton's sake? Don't people spend around 10 years going through basic education? What are they learning in those 10 years if they can't even understand a tiny bit of how the world that we live in functions?

Also, if you have read the article it's not just a failure to understand gravity, there was a severe lack of ability to apply logic (even by the TA that was teaching logic!). Well that says something about the education system.

I would argue that everyone should learn at least the basics of science, and appreciate the fact that this marvelous civilization that we are living in is shaped by the very science that they don't fully comprehend.

What people should learn is the scientific process, how does science advance, how do we know the things we know. And they should learn how much we owe the scientific method, people should know that if not for science we would still be freezing, starving and dying of easily preventable diseases, that the comfortable lives we live today is a result of scientific thinking.
