that's what I meant by education, not formal education per se but social responsibility and conscientiousness. It is easy to take that for granted in first world countries.

As for signs are not expensive. You gotta go to Brazil and see with your own eyes then.

Brazilians are hard worker, just go and check with your own eyes. The problem is a bit deeper in my opinion and experience.

You mean social norms, not "education". In in some cultures a disregard for these norms is sometimes referred to as a "lack of education", implying the individual's behavior is the result of bad parenting. This assumption is usually a coping mechanism, a simplistic attempt at a resolution of cultural conflict by asserting that one set of norms are better than those of their cultural antagonist. In cases of cultural conflict, where cultures with sets of incompatible norms attempt to coexist, the result is usually conflict followed by the establishment of new refined sets of norms shared cultures.

Road work signage is an issue of liability in the US, not courtesy.

Why so adamant that the two are mutually exclusive? The reason road work signage has been legislated (or socially defined) into an issue of liability is, again, due to education.
