The REAL root problem is immigrants coming here and refusing to assimilate.
Many come here and bring their culture with them, take advantage of all the benefits and refuse to adopt the American way of life....right down to refusing not only to speak english but refusing to even learn it.
If I had my way, immigrants couldn’t remain here permanently until they could prove at least a basic aptitude of the english language......speaking it AND reading it.
I think being conversant in English used to be a requirement.
