My son came from China 5 years ago. He spoke almost no English. Today he is fluent. There is no reason others can’t do the same thing.
Of course unless the goal of these educators is to create permanent under class that is dependent on the government. Which also just happens to also be a majority of Democrat voter.
My parents came from Hungary in 1951 and spoke very little English, however after realizing how much trouble my older brother was having in school they spoke only English with us, to the extent that sadly we did not speak any Hungarian. We did however become fluent in English and had no problems later in school. The sad fact is that those coming in from our southern borders refuse to learn English and use their children as translators and intermediaries, this is the major difference between them and European immigrants, other than the fact that the Europeans actually wanted to be Americans.
I worked in TX public education for 30 years. The high rate of Hispanics in the state dictates that all the state testing also be provided in Spanish. All other language speakers are allowed to participate in a Newcomer’s program that teaches them English but it is only for the first year in a public school. Because of the influence of La Raza, all state testing (and most district testing) is required to be given in Spanish. It is not required to speak Spanish in the classroom however.
