I need to see some real source on GDP bit. You realise this is the 5th largest economy in the world right now? If scamming Americans was that lucrative and easy then some country in South America or Mexico would be one of the larger economies in the world rather than India, because of cultural and geographic proximity. If scamming Americans was that easy, the largest source of the scams would be local. Also I don’t think economists account for the proceeds from criminal activities into GDP calculations. Even if it is in some way, crime GDP would definitely be underaccounted.
Also state support to criminal organisations would have been highlighted in intelligence reports by now and would be a major topic of diplomatic interactions. As the government is pretty incompetent it would be impossible to keep it a secret.
Your and the other dude’s assertions seem paranoid and irrational. You’re probably just a racist.
