Do most pros adopt a get rich quick or die approach?

I'm just curious as to whether most pros adopt a tournament strategy style of playing super aggressive to either accumulate chips quickly or bust out.

According to Barry Greinstein's website, Phil Ivey uses suchu a strategy to either win big in tournaments, or get out and play in the big cash games.

However, since variance and luck plays such a huge role in today's overly-populated tournaments, perhaps a quick chip accumulation approach in order to put yourself in position to play aggressively and win the tournament is better than slow, solid play.

Thoughts?

EDIT: Keep in mind that this is referring to wealthy pros, where a $10,000 buy in is spare change. They don't care about losing the money, as opposed to an amateur just turned pro, who needs to make the money or he'll die of starvation.
