"I guess I could learn Spanish, but why?"

Where are you from in the US? Im from the Atlanta area and bilingual spanish/english. Most people I know from georgia, florida, even alabama can at least understand spanish just from being around it so much. I really think to not know spanish you would have to actively try to avoid it - especially if you are young and from the city. In atlanta you can easily live without knowing any english, when friends came from south america we always found people fluent in spanish most native (at Starbucks, McDonalds, Grocery Store, shopping, etc).

I'm in Florida now but I did live in Atlanta for a few years and, if pushed, yo puedo hablar espanol suficiente para un conversacion simple. La problema es que no tengo oportunidad para bastante practica para fluente. So, I'm kind of in this half and half limbo where I can understand and speak enough Spanish but not enough that any native Spanish speaker would actually want to have a conversation with me. And for the other person who brought up the buying and selling to Spanish speakers aspect, the vast vast majority of Spanish speakers I've ever came in contact with speak a hell of a lot better English than I speak Spanish so that doesn't really make sense in practice either.

Don't forget that part of the reason that English is well known across the globe is because the US is a media powerhouse. The web is practically english, US blockbusters are seen worldwide, and it's essentially the language of international business.
