Ireland has a "It'll be Grand" culture as well for comparison. It's a trade off with pros and cons and works for some situations and inhibits progress in other situations, things often don't get acted on or resolved quickly but at the same time there is a huge reservoir of tolerance to draw on when things do get shit.
I would consider this the other end of the spectrum to countries like Japan or Germany in the way they respond to certain things. Lots of generalisations of course but that's often the impressions you get from travelling. It's very hard to be precise about big groups of people.
