How do tourney players make up for lack of table selection?

[ianlippert]

I'm mainly a limit player that plays the occasional SNG/MTT for 'fun'. Lately I've been spending more time concentrating on table selection. I'll use GT+ and leave a table when the avg vpip gets to low, and have been finding lots of success through careful selection of my tables.

I was just thinking about STT/MTT players and realised that there is no option to leave if you happen to land at a table with good players. So what do the the STT pros do to negate this? Why would you want to go pro through a type of poker where you have one less avenue to maximize your edges?
