My point is that relying on an ill-specified "invest[ment] in education" with idealistic hopes for its effectiveness is pretty much equivalent to "doing nothing." The people who most need it will not seek it out. If it works (a big if) and it's incorporated into compulsory education, it'll take at least a decade to show any results at all, and whole generation or two to work its way through the population and have a chance to actually solve the problem. And like another commenter mentioned, it's not like our current educational system hasn't been trying to instill critical thinking since before any of us were born, so I have little hope that some new investment will solve that problem.

Relying on education in this case is like having window break during a rainstorm and deciding to fix the problem by ordering a new window from the manufacturer, with a lead time of a month. That might eventually fix the broken window, but it's not going to solve the problem of rain pouring through the broken window now. If you've got a rainy month ahead, the incomplete solution may even lead to more problems, like mold.

This is a problem that requires both long-term strategic and shorter-term tactical solutions.
