> How different would you say rural JK/HP/LA/UK is?
Rural UK is much poorer than rural HP and JK.
The administrative structure of UK is very top heavy (everything is decided in Dehradun), and Dehradun+Haridwar have caused tourism and real estate induced Dutch Disease to arise. JK and HP also have a tourism economy, but also have a strong industrial base (pharma in HP, heavy industry in JK) plus more investment in higher value rural industries like food processing and fruit cultivation.
HP and JK also have a bottom up political culture with panchayats in a district coalescing into District Planning Committee that includes state civil service cadre and the MLA, so local governance is much more responsive, and has the resources and capacity to invest in infra like cold storage or make the case for an MNC to invest in manufacturing.
Basically, if local government and administration is actually given priority beyond haphazard panchayats, it makes it easier to attract build industries and a semi-industrial rural economy.
> Kerala, CG and Odisha have better rural administration than MH, TL or KA because of the absence of heavyweight cities.
Political culture is also more top-down in states like MH/TG/KA, where the CM office tends to have inordinate control over local planning and panchayat+local government funding is minimal
Even if their administrations had some interest in rural economic development (which in those states they don't), they wouldn't even have the bandwidth because there are too many districts. This is why local government needs to be invested in by states, but locals are the ones who know best about their needs and capabilities.
