yes, you are correct but somehow most PHD in economics end up doing a job and most businesses are owned and headed by people from non-financial backgrounds. Urjit Patel was an employee of Mukesh Ambani.
Nearly every business was suffering due to lack of credit and many businessmen who could have sailed thru were declared defaulters under new NPA rules. MSMEs which employ the largest number of people suffered the most as even the credit flow to the NBFCs which are the biggest lenders to MSMEs were denied credit. The aim was to somehow create a false distress in the economy and both these cheats nearly succeeded in their game. However best laid plans of mice and men go awry no matter how well they are planned. India came out of Demo in record time and it did not cause as big a set back as was expected and the GST tax collections have grown rapidly in shorter time than what was expected.
Why did it happen? It happened because the black economy got formalised even though we did not catch as many black marketeers and we had a very large tax evasion system in place which came into tax net due to GST. Though we are still far short of actual GST figures but the faster recovery shows that a very large amount of taxes were not paid. tax evasion was the norm and not tax compliance. These are the reasons why the economy suffered minimum damage due to these path breaking reforms.
I recently had to undergo IT scrutiny for my businesses for the AY 2011-2012 and I was shocked to see that IT dept had complete data of each and every transaction my companies did anywhere within India and also abroad including the data of all those with whom I did those transactions with. My own/personal bank records and of my wife were also with them. I have always done my businesses in clean manner and finally IT dept had to drop the proceedings against me. What shocked me the most was the amount of details they had. Now everything is fully connected within the financial network system of India and IT can track anything from anywhere. If you withdraw large cash and buy things in cash, they will know how much of the withdrawn cash has been used for shopping and how much has been stashed up. Not only that, if you have an undeclared source of income, your payments for services like electricity, water, food, fuel and shopping etc are all complied and your income can be tracked very easily. You may not pay income tax but the seller is collecting GST and submitting it to the Govt with details of all transactions.
