Their biggest issues stem from casteism and overpopulation.
Their lack of civic sense boils down to two lines of thought:
A:
>I'm of x-caste therefore cleaning up after myself and being polite is beneath me
and B:
>India is overpopulated, resources are scarce, I need to be hyper-competitive and selfish or else I'll be left behind
Resolve caste and overpopulation and this country will improve immensely.
