America was colonised by Europeans and also in the 19/20th centuries was a great inmigration of Italians, Spanish and some Germans and Poles, so there's not too much difference with Europe.
In the past there was no industry in Central and South America and so all the furniture and household accesories came from Europe and you still can find old European or European style furniture in old houses. Today exist local industry and all have modern style that all the same everywhere.
Climate is also important, snow almost doesn't exist and in many places is not so cold, so a poor house can have very simple windows and doors and even none!, for sleeping you can use a net hanging between two posts, but the DVD player is the same China made.

Asia and Africa are very different cultures, so almost all is different.

Stupidity also evolves!
