Naito’s Model

A Problem from Masa-aki Naito (Head of Centre for Lake Biwa environment studies)’s model.
On a plane where x=technical capabilities and an independent plane y
Assuming x>0, y>0, x2+y2<1,
Current Japan lies on point (0.8, 0.2) and a Developing country lies on (0.2, 0.8).
The point which maximizes both x+y=1 and x2+y2 is called a sustainable society.

While maintaining the y-value of Japan, how much leeway is there to maximize x2+y2?
How much should Japan move to become sustainable?
What does the y-axis mean?
