Okay it's obvious you have not read theory. Through the lens of historical materialism, aka the material conception of history developed with dialectics, we reached the conclusion that production is the chief determinant force of development, quantitative changes in production lead to qualitative changes in society.

The "mindset" from these underdeveloped countries is precisely a product of their underdevelopment, not the other way around like you imply. That is the reason we support China policies on developing global south infrastructure, because developing the productive forces (the instruments and people who carry on production) IS the way to develop society. It is not because we are blindly "chinese simps".

Obligatory book recomendation, "Historical and dialectical materialism" by Stalin.
