Why did not take action by indian government about black money?

The Indian government's challenges in tackling black money stem from a combination of factors, including bureaucratic inefficiencies, lack of political will, and the complexity of existing financial systems. Efforts to combat black money often face resistance from powerful vested interests that benefit from the status quo. Additionally, the vast and sometimes opaque nature of informal economies makes it difficult to track and regulate illicit financial flows effectively. Despite initiatives like demonetization and the introduction of stricter tax laws, comprehensive action remains a contentious and challenging issue.
