Chaturvarnya is impracticable, harmful, and a miserable failure.

Evidence

To me this chaturvarnya with its old labels is utterly repellent, and my whole being rebels against it. But I do not wish to rest my objection to chaturvarnya on mere grounds of sentiments. There are more solid grounds on which I rely for my opposition to it. A close examination of this ideal has convinced me that as a system of social organisation, chaturvarnya is impracticable, is harmful, and has turned out to be a miserable failure. — Ambedkar, B R, Annihilation of Caste_ The Annotated…, 914
