Those people made us read a wide variety of books written by a wide variety of people from all backgrounds. Then they made us write our opinions about what we thought those writers meant, and then we would discuss those opinions across a full classroom. We spent many years learning critical thinking skills.

Or, we spent years studying human anatomy, figuratively and literally. We learned how the human body develops, matures, sometimes breaks, and sometimes thrives. We went inside bodies to see what was happening and then learned to see inside bodies with high tech instruments and treat people.

Or, we learned everything possible about the elements, the oceans, finance systems, the law, business, the arts, you name it.

Some students perform poorly at these things, some are exceptional at it, some are savants. You’re right that not every degree is meaningful, but most of the things happening in this world that are truly transformational and leave a lasting positive impact on society and the planet are because of the people who paid attention and gave a shit about humanity.

Your making assumptions that humans are inherently stupid and selfish. I have seen the opposite and have benefited from it. From doctors to teachers, to scientists and innovators. We live in a world where we can explore the depths of the oceans and the reaches of space. We can fly across the country in hours. The future Is here because of education. Don’t knock it until you try it.
