One problem with the comparison is that they are all newsreaders who would be expected speak a well-educated form of Spanish. What you’d hear from the average man or woman on the street would be different I’d expect.
I notice that the women all tend to be pretty good looking. Must just be a coincidence.
The Latin American anchorwomen seemed to be almost entirely of Spanish descent, apart from Nicaragua and maybe one or two others, rather than of indigenous ancestry.
Bingo.
I once worked for a European company and traveled in France, and could make myself understood; but when I had to deal with an auto mechanic or night watchman at the plant, suddenly it was a whole different thing. Same with my travels in Italy and university language lab classes vs the street vendors in Rome or living among Italian-American descendants of impoverished immigrants.
