If India's issues were actually being seriously addressed, its true potential would be high. However, as I have noted, the country only seems to care for its elites and completely ignores its vast lower castes. So a few of its people will be be reasonably well-off, and the vast majority will be destitute; this is the typical pattern of a third-world country that will continue to be mired in third-worldom.
As I have also noted, one indication that India is becoming a serious country is if they get organized enough to start installing sewer pipes throughout the country. If the Indians continue to procrastinate, forget it.
Actually, China in 1971 was sparking with potential, true potential: the people were literate, and all of the country's issues were being addressed.
Actually, In 1971 China was sparking with the potentials betokened by closing all of its higher educational institutions for 5 years, sending its cadre of trained professional managers, scientists and engineers to farms to raise pigs, and having the country’s number 2 most powerful person and nominal head of the armed forces supposedly tried to defect to the Soviet Union.
