The reality is, America1 or France1 has tastes and sensibilities closer to India1 or China1 instead of America3. As such, there's no point targeting America3 or France3, because it doesn't dramatically grow your TAM the same way India1 or China1 could.
This is why Walmart and Amazon began pivoting heavily into the India and China consumer market in the mid-2010s.
The India 1/2/3 concept that Blume Ventures came up with is a modified version of a similar mental model we used to analyze China back in the 2000s and 2010s which itself is was forked from the principle of market segmentation.
That's why you find different companies targeting different subsegments of a market globally.
Additionally, we do live in a globalized world, so a brand that is at the lower rung in one market may try to upscale their value by targeting the upper portion of another market. You see this with Walmart which targets America2 but uses a different strategy to target China1 (Sam's Club China) and India1 (Best Price, Flipkart).
Conversely, a China1 or India1 brand can also try and successfully build market share in America2 and America3 in a manner that an America1 brand wouldn't want to do due to brand prestige implications. This is why you see SHEIN and Temu's popularity amongst America2 and America3 or Wellspun becoming the primary supplier for textile goods for Walmart and TJX.
> What's a reason that wouldn't also apply to india2,3?
If I understand correctly, it would also apply to India2-3, that's why nobody's proposing that.
