Hola Andrea, sorry it takes me a lng time to answer, but I am really busy and trying to enjoy the Festival in Cannes !
You are putting together too many things that don't mix (I guess !)
1) Mexico has a totaly other politic structure than South Africa. It had a party at the power for 70 years, in 2000 there was an oposition (right wing) that dismissed that party (The PRI) and now that the PAN has won, every thing is worse. A little bit like in France every body had to vote for Chirac instead of the fachiste Le Pen.... This new gobernment opened the country to the free market, the president had only the experience of being the director for Cocacola and is quite proud saying that he has no time to read a book !
So, it is a poor country, always has been but with a brilliant culture that tries to survive , even with the USA so close. It has a very big influence in all Latin America, because this strong culture. The former gobernment was issued of the Mexican revolution and at it start they had hudge projects. For instance the film industry. As an industry. That made more money than petrol.They could produce 185 films a year.But that was because USA was on war.... And Hollywood was not working. It was a time when there was a special crew that came together: Very big stars like Maria Felix, Pedro Almendariz, Dolores del Rio , Pedro Infante , then such a big photographer like Gabriel Figueroa, incredible directors . So to remain together, they created an UNION , nobody could enter the film industry and that was it. This period last until 1976. I startd working in short film department even if we were making long features: no way for me , as a stranger (I am french and mexican) for a sound women to even get closed to that.
Well, that'is the end of the first part of a very long story, I hope I am not boring you....
See you, Sibylle
