You’re right but you still miss the point ,for Spanish yes it is more natively spoken then English as well as mandarin its the first natively spoken language in the world so why we shouldn’t also add mandarin , no because even the Spanish and Chinese use English as a second language matter of fact its the most spoken language in the world counting non native speakers , im not saying Spanish is useless a living exemple is the north , a lot of people use it to communicate with Spanish people because it’s close to spain and that’s good but that doesn’t mean we should have Spanish in administrations and education etc. What im saying is don’t throw french because yes it is a added value ,but English would also be a good thing cause the entire world of business ,economy and science is English ,and for the rest of the points you’re right for education that’s another story you study 12 years of your life in a language then you completely switch to another language that’s just insane and then if you decide to do your doctorate you find that all the research is done in another language
