Calling one in the BB with PP

An earlier broken post made me wonder about this general question:

Suppose I'm in the BB with a small PP (88 or lower). UTG raises and all fold to me. What is my play?

SSHe tight chart says to call, but I can't see why this is a rational play with a raiser in EP.

If he's raising on the SSHe tight table (for example) and I have 88, he's about 60-40 to win the hand. If he's a little more aggressive and is raising the SSHe tight table for players in MP, he's still about 58-42.

He has to be wildly aggressive preflop (raising like a rational player would on the button, or more) before your equity goes over 50%. So speaketh PokerStove. And that's when you're holding 88. It gets worse, of course, as you hold smaller PPs.

Am I missing something, or does this just show the weaknesses of trying to play poker from a printed chart?
