As others mentioned, the main value most people get from amazon prime is free 2 day shipping - not Prime Video. So its competitors are other online retailers like AliExpress, Ebay, various niche websites, and physical stores.

Also as others mentioned, prices are set as high as consumers are willing to pay. They are forced lower by competitive pressure. If consumers decide that the service is non-essential or that other competitors offer a better service for a better price for a price lower than what the company can offer the service for, then the service will need a constant influx of cash to keep running, and will eventually be ended if it cant turn a profit.

I’ve never been to India or Japan. But my guess -

Japan is an extremely dense and walkable country. A japanese person living in the city can easily find the vast majority of their product needs within a short walk of their home. And then, with space being at such a premium, their homes tend to be small, which produces a chilling effect on their desire to buy space-consuming knick-knacks. Finally, they are close to China, so AliExpress might be a larger competitor for niche products.

India is also a dense and walkable country in some places. But it is also very poor and chaotic. The average Indian will consider a prime membership for free 2 day shipping a luxury they cannot afford. Also, the chaotic nature of… well… India, might make Amazon’s 2 day shipping promise significantly less tenable, further reducing the benefit for potential customers and driving down the price.

Edit: Also, iirc, the US price for Netflix is about $15, so it is comparable to other streaming platforms.

And also also, watching tv is a non-essential service. You don’t need to watch TV any more than Jeff Bezos needs another yacht. I’m not saying that you should suck Amazons dick or anything, but you could easily reframe this as an opportunity to re-engage with reading and socializing as forms of relaxation and entertainment.
