We cannot word it too strongly now. Free-market economics is one of history's great failures—like monarchy and slavery and torture were failures. Countries that embrace it have invariably degraded themselves, and forfeited their own hopes for peace, democracy, and prosperity. No matter what pretty stories they tell you to justify their behavior, once you give the financiers the keys to your common wealth, you can expect economic collapse as surely as you can expect the sunrise.
This fact needs to be part of our history books, forever, so when somebody suggests this to our grandkids, they recoil as if someone had just blithely suggested reinstituting slavery. It needs to be part of the canon of our great universities and our shared moral code about the role of government. The more our children remember, and the better they remember it, the more freedom they will have to make choices that move them beyond the past, consciously choose a future that is finally and uniquely their own.
