I'm surprised you follow the youtube comments! Yikes!!
But that being said, I can understand the 20:1 ratio! The people who watch this show (in India) and have the time and resource to get back with comments are usually the ones who are not bothered by unavailability of cash, or certain denominations. These are the people who have credit cards, bitcoins etc., and that's fine. What bothers me is when people get so self-obsessed that they cannot see beyond themselves! The inconvenience is tolerable to a upper-middle class people who may find that they could not buy a pack of cigarettes because the vendor won't take a credit card and (s)he did not have the right bills, but it is a lot worse for day labourers who get paid in used bills, and after a day of backbreaking manual labour has to worry about whether they have the right bills to put food on the plate for their children.
And the whole corruption argument is ridiculous! What is this, 1920s? I doubt we have any of those old school villains left who wear hats and escape with briefcases full of black money! Digitising money makes no difference to these fat cats. Where it could make an impact, other than crippling the various resistance movements, is drug dealers. Since India currently has religious right wing government that is sanctimonious about drugs and alcohol, they might be trying to cripple the drug trades. But again... street dealers will be happy take small denominations, if you are addicted you will put together the amount one way or the other, and as for the cartels and drug mafia, I really doubt they give a rat's ass about this! You can create some inconveniences, sure, but if drugs could be stopped this way, then the US would have been drug-free a long time back! I am highly skeptical about drug wars...
But to get back to the point, the people who are being affected are at a level of poverty where computers and internet are not even on their horizon. And the fact that their lives are treated as expendable is what is really worrisome. This is like living in Ayn Rand land! You can see this troublesome trend in both US and India in these young, college-educated population who think that everything is justified as long as their personal privileges are untouched, who don't care about the implications behind their conveniences, and consider "civil rights" and "social justice" dirty words! Hell, I know two PhD students at the University of Auckland, both on fullbright, who think climate change is a liberal hoax... and they are explicit about "thinking so", not "believing so", because they think admitting otherwise will cripple a lot of things they love -- hummers, private jets, big yachts, hunting etc.
People talk a lot about 1984, but to me things are beginning to look more like the Brave New World! We have made a lot of technical progress, but we have not really learned a lot of lessons! The combination is terrifying!
