Sorry to start of like this but everything in your post is illogical
1. Son of the soil does not mean son of Maharasthra, son of the soil implies son of India or daughter of India, think larger!! In the US, if a person from Texas works in New York he does not get discriminated over!!
2. Employers employ people that are employable. Why do you think the people who get employed have it easy: if they are more educated, its because they worked hard at it. My arguement here: you reap what you sow. Just because you are born in Mumbai or Maharashtra does not mean you are better and believe it or not, Mumbai or Maharashtra is still India, North/South/East Indians still don't need a visa!!!
3. Every state has this problem but lets fix the problem thats happening today. Maybe Mumbai shd be an example here and not another statistic. Marathis are known for their sense of justice and their bravery, maybe they shd lead the way!!
