Ever looked at Mexican TV? The politicians running Mexico? Almost all appear to be of European descent... no Indian mixed in them.
Yes, it tends to be an elitist society. The guys at the top stay at the top. Mexico has quite a few billionaires and a lot of very poor people.
There used to be a similar social structure in Haiti, where the lightest skinned inhabitants with the most French blood formed an elite. I think the last revolution may have changed that, but I’m not really sure.
Very politically incorrect from the currently accepted American point of view. But so it is.
