I live in city and now I prefer basmati because its less sweeter and softer. Weight gain has been a concern for me (not to my dad, he likes doing labor). Basmati also doesnt fit well with many traditional dishes, except for biryani I guess.
Cashew has become unaffordable locally because of high export demand. I find is mildly irritating. On the other hand, I earn quite well because of service export.
There's many different varieties of rice. The various regions of India use different varieites based on the type of food they cook.
I found this site that describes it if anyone's interested: https://sproutmonk.com/types-of-rice-in-india/
Potatoes are the biggest exception I can think of in the UK. Largely grown here! Could believe it's similar for retail rice in India for similar reasons. (That doesn't work for say wheat flour though. A lot grown here, but best you can do is pick your protein %. I'm also not sure if you should care about more than that though - milling aside.)
I'm not talking about just India (nor just rice) if that's the confusion - I don't know where I'd personally go for a choice of basmati cultivars, but there's probably things (potatoes?) I have more choice of in the UK than there generally is in India.
In other words the special part here, along with the quantity, is that the process was deliberate and encouraged. There are like 110,000 identified cultivars of rice in India. There are special harvest festivals that specifically encourage the discovery of new rice varietals which are then shared in these festivals.
The British kedgeree (which has its origin in khichdi but frankly is quite different - like a breakfast biryani of smoked haddock & boiled egg; generally no daal) doesn't at all share that.
Also we used to cook Tehri/Tahari vegetables/ rice(non-basmati), heavy spices in pressure cooker. Though nowadays Biryani/Pulao has taken prominence.
In the UK I think I'd have a hard time getting anything other than generic 'basmati' (which afaict just means Oryza sativa indica - it could be IR24, what you're calling basmati, anything else in the subspecies, or some blend with the yield & shelf-life & availability properties they wanted) that would be at all suitable for (my attempt at/interpretation of) 'Indian' food.
Whatever it is I suppose I subconsciously agree it's bland - I tend to cook it with some rai/jeera/ilaayachi/laung depending.
(Edit -) It just occurred to me that the cashew issue is probably not helped that they're hardly cheap here, largely eaten as a snack (roasted & salted) on their own - which supports a higher price, I suppose, than more common use as more of an ingredient (e.g. kaju katri, ground up in creamy dishes) in India.
It’s relatively easy to find any kind of rice in countries with significant East Asian diaspora like England provided you are ready to buy largish quantity (10kg). It’s highly likely there is an Asian market near you with a surprisingly large selection of rices (not necessarily on display) and which can get you other kinds if you order. It definitely is more involved than going to Tesco but far from impossible.
There are many varieties of Rice and Basmati is just one of them. In India it is used only for special dishes like Biryani/Pulao/etc. and not as a all purpose everyday use Rice. And it is also a higher margin crop well-suited for exports.
