Fact is that most of India's 'Big' corporations are publicly listed so even 'Billionaires' don't really concentrate that high a % of wealth as a proportion of GDP. Plus, they key question is for a country doubling it's economy every 8 years be compared to a rather stagnant economy like yours?
a) When we had a YOY growth rate of 4%, we used to call it 'hindu rate of growth'. You are wobbling in that range frequently. Whatever the indicators are, we'll be doubling the positives in 8 years.
b) While u refer to our Per Capita as being equal to yours, what you don't point out is that we were waaay below you not too long ago. At our rates we're now ahead of you- be twice as high as you in 8 years & four times in fifteen years. An unbridgeable gap even if you worked hard.
c) It's a misconception that only urban india is booming. Rural India is growing rapidly. Most importantly, while u ppl keep bblaring about farmer suicides, what you don't realize is that % of rural incomes on farm income is steadily falling- a FUNDAMENTAL shift that has long term implications.
d) We've build 100,000 Kms of rural roads and thousands of kms of world class national highways to connect our hinterland (so that 200 km motorway you keep bragging about really don't impress us at all- maybe an achievement to u but is nowhere close to our standards).
