This article seems to be totally biased and not entirely aligned to ground reality. It's what the general people call as a "hit job" by the (mainstream) media. Most of the points raised in the article are in line with what the opposition political party - Congress has said, a party universally known for corruption & for playing dirty appeasement politics, a party that has kept India backward & in abject poverty even though it was in power for the last ~70 odd years.

Yes, there were hardships. But Indians can see the benefits in not only black money reduction, but also in decrease in tax evasion, digitalization of the economy & also reduction of terrorism & anti-social elements like mao-ism, naxalism etc.

In any case, I think we should try & maybe fail & learn from this, rather than let the status quo of affairs go on as it has been since India's independence in 1947. This is probably the first bold move ever in Indian economic history.
