Am I Playing Too Tight?

I enter 1$ tourney's on Pokerstars, MultiSNG and Regular, and 5$ Single SNG, and it seems like I'm always trailing. I know I play tight, but I never get good starting hands. I end up almost always getting squeezed out by the blinds, but barely hanging on by strings. Why is it that it seems like some players can rack up chips and be at the top of the board, while I'm always struggling towards the bottom.

I do relatively good in all of the tourneys, but I can never seem to be on top where I have leverage over everyone else.

Anybody have any advice? I hope I made it clear what I am asking.
