Another difference between India and Pak - Human capital at the very top
The intellectual elite in India ranks not too unfavorably with the best in the world, unlike Pak
Pak in contrast has less extreme poverty than India

Count the # Pak students in top courses vs the # Indian students
Count the Indian professors in faculty vs Pak professors
You'll find a huge gap even if you adjust for population size
For one thing - The region that is Pakistan today had a significant Hindu population no doubt prior to Partition
But this H population was concentrated in the large cities, and among the bourgeoisie classes
This class moved en masse to India circa 1947
But I don't think the replacement was anywhere close to commensurate
In Pakistan you have biradiri culture (tribal system) as opposed to a caste system
In India, you have a more individualistic society, and a somewhat less egalitarian culture, with enclaves of excellence at the top with several overachieving elite groups
