1. Most Indians are fatalists who typically blame themselves for any shortcomings in their lives. They don't blame the system thus they don't feel the need to change the system. There is a saying among Indians which in English translates to "Spread out your legs only as long as the mattress". Most Indians are not ambitious, especially the vision they have for society.
2. When many Indians organize they do so as a mob and not as a scientific group with progressive aims. Being extremely religious adds more fuel to this fire.
3. Many Indians don't have empathy. Even the report of 300,000+ Indian farmers having committed suicide within ten years because of artificial, socio-economic reasons, this doesn't move many Indians.
Thus I think these three points are why many, if not most, Indians, including the middle class, especially the middle class, doesn't rise up in revolutionary thinking.
Maybe the UNO should govern India for some years.
As a Chinese I am very familiar with those national characters. Why is that? Because I am Chinese, and I am familiar with Chinese history.
China once was a noble nation, back in 202 BC – 220 AD Han Dynasty, 618 to 907 AD Tang Dynasty, those Chinese are so different from those in Qing Dynasty, so different that they are two kind of species.
What changed? National characters. In Han Dynasty, they are brave solders, hard working farmers, discipline citizens. In Tang Dynasty, they are poets, diplomats, innovative. In Qing Dynasty, they are coward, selfish, undisciplined, shortsighted, inward looking, greedy, self-destructive.
Who changed the fate of China? The CCP and the greatest revolution.
India never went through any revolution in past 100 years, the legacy, good and bad all kept.
The old colonized society, good and bad culture, religions, cults, landlords, Zamindaris, they kept their influence and increasingly more influential.
The India society is mosaic, factions interests dominated, chaotic.
The leadership is absent, busy on elections after elections, please voter bank, putting national interest aside.
The India nowadays and Republic of China ruled by KMT back in 1930s are perfect clones in my eyes.
