I guess it was working very efficiently at dividing the society which made it very easy for outside forces to conquer India multiple times. India has seen so many waves of invasion where Indians are fighting other Indians.

I think that's an oversimplification. The varna dharma system was no in place universally, as all over the world, humans are still human and subject to corruption.

Classification is segregation if people are free to take any job there is no classification required. It was a short sighted system, a modern economy works by people participating in it by exchange of skill/work for money. There is no scientists caste , no computer programmer caste all that exists is peoples skills, ability to up skill and take a job as they qualify. Todays Programmer could be tomorrows priest, CEO or politician. Also economy and society as a result is much wider than 4 Groups of the Hindu caste system. It is a terrible system no matter how you look at it. My understanding is it was a reservation for Jobs for certain class of people from them to their sons and daughters which was codified in religious texts or law giving books of the time. Not only something like that vicious but out right unethical.
