In re: What Mumbai can tell us about 2029.

Upper middle class & above Hindus in Mumbai would never bother with protests because they would be focused on academics & resultant private sector jobs/professions. 

Even a paper leak would mean nothing more than annoyance for them.

Government jobs were seen in Mumbai as something for poor & lower middle class people & government servants were seen as people who were to be avoided expect when required to be bribed.

Growing up in Mumbai , I had never heard about public service commissions till I studied about them in college. The only people who I knew to have appeared for public service commision exams were ONE from my locality (now an IPS) & ONE relative who I have met a few times. 

The reason for this was Mumbai's business & professional culture and it's vibrant corporate sector.

If upper middle class & above Hindus in Mumbai are joining anti government protests today it's because of how the economy has changed over the last few years.

Most such protestors in Mumbai likely do not care too much, if at all, about politics or issues like supposed vote-chori. 

However they are frustrated and restive because of lack of prospects in life.

I do not blame the government of the day for it because nobody can actually change economic realities & indeed achievement oriented mindsets.

Thats said, being in power, the government of the day should be worried if this is happening in Mumbai.
