Germany has tonnes of manufacturing and brewing businesses that are branching out into the United States. Anyone who needs a job and actually wants to earn a decent amount of money would be stupid to not want to learn German and sign up for such businesses.
German economy > the rest of Europe > United States
Thus, Americans should learn German in school instead of Spanish or French.
French is a shit language spoken by arrogant dirty whore pigs in a disgusting and ugly country. Nothing of use comes from the French that you cannot get at a higher quality (and probably cheaper) from Germany.
Spanish is spoken by some of the poorest and least educated people in the world. Do you Americans REALLY want to talk to immigrants that are too ignorant to learn the language you speak before they come to your country?
Also, German is similar enough to English that learning it would, for the most part, be easier than learning French or Spanish.
Oh, and German chicks are hot.

If there are any languages Americans need to learn, they're Mandarin and Cantonese. And I didn't realize people spoke French in the US outside of Louisiana or on the border with Quebec.
