Because India is a tightly-controlled socialist toilet...whatever viable economy there might be is conducted away from the grip and grab of the COMMON GOOD as such is envisioned and imposed by the would-be master with envious mob.
Yes...there is the economy that the government observes...and...that "front"...that "facade" hides what is really occurring with respect to the market place. Indeed...the real action is in the alleys...behind those walls...and...somewhere other than where MODI and his "GRAB-TEAM" can look.
Knowing about this under-the-cover marketplace...Srikumar Misra went to BHUBANESWAR...one of the biggest socialist toilets in the world...and...began to produce milk using the cows the HINDUS won't touch. FREE MILK...FREE COWS...300 million(+) bovines...with available milk should someone find a way to corral and extract economically that "walk-about-milk".
MISRA developed a collection system that used sunlight to run the engines and pumps...sterilized the milk using specialized gamma ray generators...and...packaged the milk in a special-plastic container that kept the contents fresh and delicious for 90 days. Such product in the squalor of India was needed...with smartphones now available...and...with the blessings of the 12,000(+) gods of India...he might very well succeed,(WSJ A-1;07-07-18).
