if you think that the caste which you say as backward are only meant for cleaning filth, you are mistaken by it.
we live in a world marching towards 22nd century. thoughts like these reflect your rotten mentality only.
reservation has given a weapon of undue advantage. performance should not be compromised. everyoune wants to excel and achieve the heights. let performance be the criteria. you discussed about financial considerations. i am of the view if a candidate can achieve a height, let govt comes forward to aid him/her in studies so that finance should not crush talent.
anyway, govt has introduced some measures in the form of educational loans. more can be worked over better options.
why reservation?
hope you will look with a broader perspective without dividing students in fields like cast or creed.
