The remedy usually proposed for this mismatch is education. Indeed, a top-notch school system available to all is hugely important. But even with the finest educational system in the world, a significant portion of the population will continue, in a nation of great abundance, to earn no more than a bare subsistence.
To see why that is true, imagine we lived in a sports-based economy. In such a marketplace, I would be a flop. You could supply me with the world’s best instruction, and I could endlessly strive to improve my skills. But, alas, on the gridiron or basketball court I would never command even a minimum wage. The brutal truth is that an advanced economic system, whether it be geared to physical or mental skills, will leave a great many people behind.
