Can you explain then why Dr. Ambedkar asked for only 10 years of caste-based reservations and to be done with it after that? Did he not know of this statistic when he asked for the reservation to be scrapped after 10 years: https://www.deccanchronicle.com/opinion/columnists/290917/ti... ?
We continued to have caste-based reservation for 70+ years. That is almost 3 generations. We are well into the 4th generation. This is more than sufficient time for uplifting lower castes. And let us not forget that access to education and industry has improved exponentially in this period while it wasn't available previously.
The time has now come to move away from caste-based reservations to income based reservations. For how long will we keep enforcing caste in everything? Then the upper castes will also enforce undeclared caste based reservations in private sector because they did not get the same treatment in Government sector. Isn't it? This will just end up being a never ending process of one trying to out-do the other. You now have political parties specifically oriented around Dalit issues like the Bahujan Samajwadi Party. Do you have a political party specifically oriented around Brahmin issues? Nope. This shows that the system has empowered the lower castes well enough already! So we can now move to empowering the actual downtrodden in society: no matter what caste, creed or religion they belong to!
