I don't see how it would make a huge difference. It might be a fun topic to talk about with strangers and in parties. Minors are usually to either compliment a major or taken for a student's own interest. Of course double minoring would take more money but if you're okay with that then go for it. However minoring in English and Sociology won't really get you anywhere. It doesn't even get people who major in it anywhere. Neither does PS if you don't plan on going to medicine or law school.
English majors like to say that majoring in English teaches them to write well. I can write well, I can write essays, short stories, reports, you name it and English isn't my major. That's why colleges make most freshman take English 101 and English 102 so all majors can write well, analyze, think critically and go anywhere and be able to communicate through writing.
English might be interesting to major in, but an employer wants to know what you're going to give back to the company. A nurse can take care of sick people. An accountant will analyze the company's financial state and tell them what direction they should head into. A programmer writes programs and applications that will improve the lives of computer users.
If you major in English it says you can write essays, analyze, think critically but it hasn't trained you for anything more specific. Its not a bad thing but English just doesn't get you hired much. Because other people who had more specific majors can do what English majors do and more, because their degree was more specific and because as freshman they took English credits and already know how to write, analyze, communicate through the written word.
You really ought to get a more specific major. PS and English majors are a dime a dozen. You need to support yourself after college so it makes sense to go for a more marketable major.
