What are TNC's. And are they good?

TNC's are companies that operate in more than in one country. They expand internationally and can help themselves out and countries too. India is a very nice place for TNC's as their large pool of labour and low wages makes it very nice. TNC's provide jobs and can help the infrastructure while the Indian government gets taxes from them and their employment rates go up. However TNC's could drain resources from their local community or the working condition could be shambles.
