Nobody gets rich from everyone staying healthy all the time. The gears of capitalism will still keep turning if its populace is made shallow and dull by bad education and crappy art made for profit. Billionaires aren't made by leaving forests and oceans unmolested, consuming less, mining less, drilling less, using less energy. The economy doesn't soar when the world is at peace and nations are working together in harmony.

If you programmed an advanced AI to arrange human behavior solely around extracting the maximum amount of profit possible using existing technologies, its world wouldn't look a whole lot different from the real one. We're being guided by unthinking, unfeeling systems that don't care about the good of our minds, our hearts, our health, or our biosphere, which will sacrifice all of the above to accomplish the one goal we've set them to accomplish.
