What is the linguistic term for an environment where parents teach a second language to their children in lieu of the parents' native language?

Question

For example, Lebanon is an Arabic-speaking country. However, many parents insist on speaking to their children exclusively in English or French and refuse or severely limit the use of Arabic. Is there a linguistic term for such a phenomenon? Does this phenomenon occur in other countries or societies? Is it detrimental to language acquisition?

Answer 1

It may be simply a mindset of being colonized for many years, displaying the understanding that you can only be successful in life/educated if you speak the language of our colonizers.

Not sure if there is an official word for it. I could think of a few unofficial ones.
