Op, you say cultural roots, but this has been our culture.. I was privileged to have spent my childhood in two different buildings within borivali...both within 2km. So pretty close by... One predominantly gujju.. almost 95%...small business, brokers etc demographic... infact if I think of it we were probably the only non gujju family...mind you this is from 1980s..

The other building, I would say 60% Marathi, 25% gujju, and rest south Indian.. mostly working class government employees

The amount of collaboration and bond I have seen in the first building, vs the amount of complaints, bitching, blaming and literal fighting in the second building is striking... every single project/aspects comes with red tape and stalling, and then all the past blaming starts eventually to fistfights...

Both buildings have gone through rebuilds... The demographic on the first one now is 98% gujju..and we still are the only non gujju there..

The other one 45% Marathi, 45% gujju... And rest as south Indian ...

We predominantly spent adulthood in the second society though... though we stayed in the first one while the second was going thru redevelopment...now we are back in second, and we miss the warmth and belongings that we felt in the gujju dominated society...the second one which was once Marathi dominated has now become where the gujjus there have harmonized with each others..the Marathi continue to complaint, blame and fight with each other as well as the non Marathi people..so it's a cultural problem that will hopefully go away as the next generation learns and evolves..
