No end to job reservations

I have been thinking about reservations in jobs and also in the exam cut offs.

Reservation was given to the Scheduled Castes and Tribes because they had no land ownership and they were also oppressed throughout history. To uplift them from poverty, they were given these reservations.

I don't have a problem with this part.

Say, person X(Gen 1) who is from a SC, gets a job. He marries and has kids. His kids(Gen 2), also SC, will get jobs. These kid's father had an income, so it is not like they were extremely poor. As we move down to Gen 3, I believe they would not be poor anymore. We can say that they have been uplifted from poverty.

Should these Gen 3 kids be getting reservations in Jobs/exams? These Gen 3 kids now have money and resources and links/contacts. But still they will opt-in for the reservations. They will eat up jobs which should instead go to poor people from the SC/STs.

Also, by not ending the reservation for them, even after 3-4 generations, we are implying that no matter how much money you have, you will always be of a (so called)lower caste.

I believe Multi-Generational reservations are holding the poor people of SC/ST and India back.
