  When I see a mestizo, I cant see his part of spaniard (white) blood. What I see is an amerindian (mongoloid). In fact, on the contrary people think, spaniards didnt mixed very much. And if they did, it only happened during a short time. The majority of the South and Central America population (except Argentina, Uruguay) is native or mixed with black. These lasts are called zambo as the president of Venezuela Chavez.  In the original caste system a mestizo would be 50% white 50% amerindian, nowadays they have mixed and remixed among themselves so much that the white portion must be less than 10%, it depends on the country though    Chavez is just a mestizo, a zambo in the caste system was a 50-50 mix of negro and indian, with the mixtures an remixtures of the average venezuelan I doubt Chavez is 50-50, he must have a small white portion, a heavy black portion and the remaining indian, so as I said before the caste terms are deprecated for the actual scenario, but mestizo in the sense of mixed one fits perfectly.    I have a theory regarding mestizo-american countries: they are basically the mix of the social scum the earth, let's see:     the indians came from asia, asians in general are hard-working, amerindians are lazy, maybe they were the lazy scumbag asians that the other asians expelled from their lands and ended up in the americas    the negroes that were brought were enslaved by their own kind, so they either weren't very popular in africa nor very bright-strong-fast-brave, they got caught by sub-stone age negroes anyway...     and finally the whites that were sent to the americas during the colonization efforts, the ones that mixed with the other scum, were the white thrash of Europe, all the undesirables were sent to the colonies with promises of fame and fortune, criminals, pervs, homos, Jews, deviants, etc... the bottom of society, blend it all together and you get a 3rd world banana republic.
