It's been a while that I've been to India (last millennium...). Back then, the Times of India had pages and pages of lonely hearts ads in the back, or rather, matrimonial ads. They were sorted by caste, though there were two special categories for NRI (Non resident Indians, i.e. expats) and MBA (yes, Master of Business Administration graduates) - they seem to transcend caste. The ads typically specified the industry and income of the candidate (or their family) in LPA (lakh per annum); some would specify that "caste no bar", and a few allowed that the "bride may apply herself" (rather than the family).
Quite eye-opening. I wonder how things are today.
