I see it as a complete political decision from the Maharashtra govt. Its just for votes.
If you talk about 80% employment from Maharashtra then what about the upmost priority of MNCs to enter in India. Their priority is to get the skiiled resources. May be that MNC set up its plant in Maharashtra but cannot take resources more than 20% from other states! Hence, not capitalizing their objective of doing business in India. Therefore, 20% companies will stay in Maharashtra & 80% companies will set up their further plants in other states.
I feel its an idiotic move by the politicians. Quite shameful!
