It’s sad but true - many want to come to the US for the benefits (including earning dollars, of which they send a sizeable amount back to Mexico) and don’t want to learn and abide by our laws, learn our language and accept our culture.
One of my grandfathers came from Austria-Hungary many years ago. He learned English (not easy for him - no schools to do so) as did all of his 6 children, upon his insistence. They were Americans now.
Exactly. Back then the belief was in order to get ahead one must speak English.
