With information being shared freely across the globe at the start of the 21st century, why didn’t countries like India, Vietnam, or those in Africa leap forward to become first-world nations right away? What stopping them ?

I mean, Korea and Japan developed rapidly about 30 years ago, even when conditions weren’t very favorable for them. Or People call Korea’s rise the “Miracle on the Han River” because it is a Miracle ? Does that mean there will never be another newly developed country again, besides China?

Even if I have all the blueprints for building a car or a washing machine, that doesn’t mean I can just build one to improve the lives of people around me. Is that what patents are trying to say?
