Factor the ecosystem - the supply chain of talent, housing, spenders, taxes, etc - that accompanies the capital. It's the boomerang that happens in the Silicon Valley every day. If you go to Bangalore you can see the dramatic difference to the rest of India. I think Bangalore is 15% of India GDP like California. The Silicon Valley is a wealth factory - where a few billionaires are minted monthly - with many millionaires as the icing.
exciting; this is kind of capital and fdi that we need to pursue; 1000 such companies each getting 3m dollars a year as fdi; easily 3B dollars; or about NEW SGR every year.
