Do we really pay that heavy a price for "Longtermism"? What about "Shorttermism"? On a comparative scale, which seems to have the heavier price, right now?

How much "Longtermism" is there, really, anyway? Reading TFA I see it is small and mostly a philosophical idea that has some proponents with lots of money. Yet those same proponents are also fully invested in shorttermism via the corporations they own.

So, I see a lot of lip service to longtermism but no real traction on the ground that would allow me to believe that we are paying a "heavy price" for it.
