Black/corrupt/illegal money in foreign banks is coming back to India via Hawala/FDI/FII/NRI/PIO investments. This money is used to create jobs in the economy. Your anti-corrupt agitation will not create new jobs in India.
It is because of corruption and rent-seeking attitude of government we dont see more and more business rising up in our country. That is the reason if India can generate Y jobs every year currently it is generating on 0.1Y. Only when we have more transparent and thinner government we can expect to have more jobs.
Black money is not going into renewable energy, medical research, startup funding, education and so on. It is going into real estate, government tenders and so on.
