Ditto DeepShadeOfBlue and Jae B.! I'm an English major and I think that it has prepared me pretty well for journalism. Although going into this profession isn't likely to make anyone rich to be honest (oh, the things you do out of love!)
But I think an English major can prepare you for pretty much everything except for the more science-y fields. Law might be a good idea if you want payoff, but I'm not sure if they would accept people straight out of undergrad unless you've done a lot of related things on the side. Business and management requires good communication skills, which I'm sure you have in plenty. You can also consider more specific fields, but only if you're really passionate about them, like sociology, history, social studies, ...and everything else, really.
I suggest choosing professional degrees instead of academic/research ones for better payoff, but before that I think you should find a field or profession you really like before going to grad school. I think it'd be better for you to try out internships or shadowing people whose professions you think you might be interested in. Find something you're willing to do full-time for free first, and then go ahead and get your grad degree to earn money from it!
