OTOH, quite a few of the Indian billionaires are old money and inherited wealth -- Mittal, Ambani, Birla, Godrej, Mistry, Agarwal -- and the others are largely in "technology" (incl pharma?) sector.
So, part of it is India's own history as a capitalist economy and its own massive class divisions -- whacked in China by the revolution -- and part of it is the "reforms" -- privatisation helping push up the fortunes of the old rich and, yes, global capitalist economy -- outsourcing, M&A's, JV's, reverse FDI's, etc.
Don't know what the gap was like, say, 20 years ago between, say, the Mittal's and the Indian labouring classes, but couldn't have been small. It has probably grown much wider, as the top layers now join the world capitalist class, while the bottom remain within the Indian working class. Segmented markets are great for the rich.
But even for the old rich -- seems like a disproportionate number are Mumbai-based: part of the old global economy?
