I don't believe the pinnacle of American enterpreneurity, the frozen-then-deep-fried cheesecake-on-a-stick, is currently exported.
Each new niche creates two new niches: one on each side.
I ate deep-fried oreos at the state fair this year. Because deep-fried snickers bars are just so
passe.
Fooker, if you have a skill or craft you could translate that into cash. I knit, and there are lots of people who sell their own knitting designs or handknit objects online, or offer free knitting patterns with adsense ads. My spouse has also made $100 over the last 4 years by making a website of
Spanish Flash Cards, but then again he has a really good google rating, which is hard to get unless your site has been around a while. And it's not a lot of money -- $25 a year -- but he also hasn't touched the website in that time either so it's sort of residual income.
Online businesses are just like any other business venture, think about your personal strengths and skills, and put those to use to do something you find interesting and will be good at.
But don't quit your day job.
