The is literature (in Sociolinguistics) that states that the minorization (social) of a language can contribute significantly to the minorization of the collective identity of the linguistic community that speaks that language.
Very difficult to say, considering the economical and political factors which play a far more crucial role in this process of “minorization” than language.
Jinan F. B. Al-Hajaj Yes, I agree, it's a very complex matter, in which it matters economics, politics as well as cultural questions. In fact, I think cultural assets/history prevails in order to excerpt influence in the impact of economics and politics. In this case, maybe it is possible to say that ideas could move/make go forward "minorisation" of the other (languages, human groups, etc.).
Vicent Martines There is also the power and prestige that come with being able to speak English or French for instance. Nowadays, employers favour those who are fluent in English, marginalising and almost excluding those who don’t. so as you mentioned , it is very complicated and linguistic diversity is at risk today as it was in the time of colonialism.
Jinan F. B. Al-Hajaj Yes, in short, the linguistic "minorisation" is just a kind of expression of a "colonialism" in terms of the attrition of the language which seems "lay" in a weak position (speakers number or economic situation or military forces or...simple perception of an not always objective reasons based prestige) by another one/s in a improved situation. It is a "colonialist" situation, but more "refine" that the colonial regimes in 19th C. or till the end of Worl War II. It is about the roots of the problem that we investigate...
Vicent Martines That’s very true since long after colonisation ended, the languages of the colonizers hold sway. Let us not forget that the technological innovations , computers, mobile phones, etc also empower English as well.
