Transition from agriculture to developed economy
In an isosceles triangle with a sharp apex, Malfatti's circles occupy only a modest fraction of the total area; other algorithms do much better.
Alternative to Malfatti's circles in a sharp isosceles triangle: three circles stacked with a greedy algorithm occupy nearly twice as much space as Malfatti's circles.
