In the states we have manditory foreign language for highschool, wheras in the rest of the world I think students learn a second language really younger. The choices were Japanese, French, Latin, Spanish and German. And honestly I wanted to learn Cherokee, the language of my people, or even Miami. However, the ways the US view the First Nations is abysmal, if you had not heard about the recent happenings with the Sioux nation, look into the pipeline protests, particularly the Morton County Sherif's Department.
So I thought, as a person displaced from his tribe, what language would suit me. Spanish is the language of the enemy, I mean I'd heard all about Portugal and Spain's use of slaves and rape to assimilate the first nations. Japanese has too many characters, and French is like, so doesn't like Americans. And Latin is sort of dead. I ended up picking German simply because my step dad at the time spoke it so I could practice with him.
I think all those listed languages are lovely, and when you strip away the histories of their people, they are indeed wonderful speakers around the world.
Now some of my favorite stories from history are like Lapu Lapu, the hero of the Philippines who killed Ferdinand. And it goes on. I have studied German, Russian and Cherokee, as well as some Hindi and other non Cyrillic languages. I'd even spent some time learning Summerian for the sake of understanding language more. In all cases, the speakers both assimilated and natural born, created their own colloquialisms that I feel we should respect. Even in english you have British and American variants, and they both continue to grow.
While I respect that you may be frustrated with the preservation of the Spanish language, I just feel it's not as great or innocent as one might imagine. I think of all the battles fought under the Spanish flag, the shift from a word to a new word should be the least of your worries 
Anyways, have a great day. And yes, American education is really #1 for illiteracy and early incarceration.
