Always found it weird how the establishment touts black money as the root of nearly every problem, and also their idea of fighting corruption by eliminating black money. Isn't it supposed to be the other way round?
IMO, black money is a boogey term flaunted at citizens by successive governments:
1. To coax income tax from folks who haven't figured (or don't have) the means to dodge it. This basically includes everyone who is not mega-rich or a politician.
2. And to show themselves to be "fighting" against something (for the people, no less), all the while conveniently ignoring the real issue at hand - corruption (and mismanagement, to an extent).
Also, it's hard to believe that getting rid of income tax affects state revenue to the point of crippling the country, as often claimed. Income tax very likely makes up a small portion of the state revenue.
Finally, at the risk of stating the plain and obvious - contrary to what people are led to believe, nearly everyone here pays (ever-increasing) taxes all the time, in one guise or another - GST, petrol/diesel, etc.
