Your answer lies in one of the comments itself.
If I say about my state Kerala, anybody who have visited a GCC country will find Kerala Muslims running businesses there especially super markets including the LuLu Group. Its the same back in Kerala also. On the otherhand Christians dominate the finance sector. Some people are comfortable with some sectors.One cannot attribute the low presence of Muslims in the IT industry solely to discrimination.
Cultural factors come into play here. For one, most conservative Muslims do not allow their women to work. So that robs 50% of their workforce right there. And you cannot blame Hindus for that.
Also you will find that Muslims are overrepresented in other professions such as real estate brokers, furniture shop owners, provisions merchants, dance teachers, gym instructors and so on. Virtually every other real estate broker I have come across in Bangalore is a Muslim, even though they form only 10% or so of the population. Also, anecdotally, I found Muslim guys to be overrepresented in Page 3 photos in Bangalore newspapers (often with a pretty Hindu girl in their arms). Whether that amounts to them being "discriminated", I don't know! Although surely Muslim women seem to be in that regard! Not to mention the number of Muslim male actors in Bollywood, where they are clearly overrepresented! Maybe Hindus should demand reservation for acting in Bollywood hero roles!
Let's face it, every community has a proclivity for certain lines of professions. Malayali Christians dominate the BPO/corporate training space as much as Tamil Brahmins dominate IT. People from North East states dominate the hospitality industry. It so happens that each is comfortable sticking to certain lines of profession because this is what they are most familiar with and have networks. As long as everyone is happy and has a decent standard of living, I don't see anything wrong with it.
Reservations are of no use if there are not enough qualified applicants from a community in the first place. In most cases, it it not because they get discriminated against in college, but because they choose to get into other lines of work, due to influences from within their own communities.
As far as schools are concerned, I don't care what the blog says..Its all about money. If you are able to shell out money in the name of donation or development fund or whatever name they call it, your kid will get admission. If you don't have money, there is always the Govt schools with mid day meals.
Almost every community in India runs their schools and if its a minority run institution, there is provisions by which you can reserve a certain percentage of seats for kids belonging to that community.
Anyways I would like to know the % of Hindus & Sikhs in PA.
