I support English as the official language of the United States. Simple reason: efficiency. Cost savings. Look at Canada. Look at the EU. That tells you everything.
Canada has English and French as national languages. 90% of Canadians speak only English. The EU? Twenty-five official languages. Citizens of both Canada and the European Union gripe constantly about the costs. Every EU proclamation, every law, translated and printed in 25 languages. German to French. French to Spanish. German to Latvian. On and on.
This isn't a new idea. The Romans declared Latin the language of the empire. Trade got easier. Government got easier. Education got easier. Latin drove their advances in math and science. And because everyone used it, all that knowledge got written down, preserved, and understood by future generations.
Now, the United States hasn't had an official language until yesterday. But let's be honest. English has been the practical language of this country for a long time. You want citizenship? You must be able to read, write, and speak English. That's already the rule. Saying "English is the national language" just states plainly what everyone already knows.
Tons of immigrants arrive with solid working English. Many consider it a prerequisite before even coming here. I work with quite a few folks from other countries who learned English before setting foot in the U.S. Most speak excellent English. Years of study. Serious money invested. Why? Because they know that's how you access everything America has to offer. Showing up without that preparation? Recipe for frustration.
Benjamin Franklin actually worried about this same thing. Huge numbers of German immigrants pouring into Pennsylvania. Few spoke English. Franklin thought everyone would end up speaking German and English would become a second language in the colonies. But those immigrants learned English. Generations later, their descendants all speak it.
Making English official sends a clear signal. Learn English to make a life here. Best to get that education before arriving. Already here? Enroll in classes. Make that investment. Millions before you did the same.
