Kt ... okay, so some might disagree; but, to answer your question, "What constitutes needing credit?" Simply -- and unless you're a Kennedy or a Hilton or a Gates -- life. Unless you can pay cash for everything you might ever need or want -- like a house or a car and braces on your child's teeth, or as in my 21year old daughter's case, all 4 inpacted wisdom teeth surgically removed at one time! -- you need credit. It's just become a fact of life, and I'm near old enough to remember when it wasn't!
