When you compete in powerlifting - you're not competing against the blimps, unless you are one. It's a level playing field. Sucking a judges dick isn't going to give you 10 more pounds on your squat. If you feel inadequate, generally you'll fixate on the blimps because they are the ones who are lifting the most, but that's not how a meet works - those people are not considered "above" the lower weight categories. In fact, generally, the "star" of a powerlifting meet is the guy with the highest bodyweight to lifts ratio.
