Why all this nonsense about English only?
I came from an officially bilingual state, New Mexico (Spanish and English).
I now live in a bilingual country, Canada (French and English).
Switzerland, a prosperous country, has four (or is it five?) official languages.
Republic of South Africa has eleven official languages.
Spain has two, and is moving towards three.

I bought borscht and cabbage rolls in a Russian delicatessin yesterday- everybody in there speaking Russian and it was a busy place. Name your flavor and it is there in the city; great variety.

In San Antonio, Texas, where I lived for a while, the languages of business in most stores were English and Spanish, no problems getting served. A city of well over one million, 60% hispanic. Remove the undocumented and speakers of Spanish and the economy would collapse.

In Vancouver, Chinese and Vietnamese are spoken commonly. My son has a Pakistani and an East Indian in his business who can handle immigrants from those countries in their own language. Other firms have Chinese and East Asian employees who deal with the growing Chinese, Korean and Vietnamese trade.

Being essentially unilingual, I feel myself uneducated.
