1. Skilled workforce
2. Infrastructure
3. Rule of law
Present India lacks all 3 in one or the other way and indeed moving towards authoritarian government with shutting down internet at will, arresting people for post critical of govt or it's ministers [1] [2] [3] [4]. Looking at what's happening with economy, fudging economic numbers, large young unemployed youth, faltering manufacturing sector. These are ticking timebomb.
Obviously the major beneficiary has been south east Asia, especially Vietnam. Not sure India can take advantage.
