Learning to cook wasn't high on that list when tech salaries were great, delivery was cheap, and housing wasn't (completely) unaffordable; now that I'm nearing my 40s and have to stretch even a six-figure salary further than before, suddenly learning to cook is a necessity.
Good people are always changing in some way. Making public education free encourages lifelong learning and builds a more adaptable human for times of crises. It's good survival strategy, that also just happens to create a more fulfilled human being.
