I agree with you friend. The categorisation should be done incomewise. Not all the SC/ST are still poor, not all the BC/OC are still rich. Poor gets the opportunity with quota and becames rich, rich not gets that opportunity and becomes poor. Everything as of now is depending on income and financial status only, so my view is to announce the category with respect to the financial status of the individuals. All the quota shall be according to the financial status only. It is Irony that a person who is already rich gets the seat in a college with quota, not with his marks, and gets concession in paying fees also. This is done only in India I think.
