I have no idea why people __LOVE__ making these statements. 2008 was something that affected mostly the US and while it affected the rest of the world to a certain degree, overall very little changed.
Before jumping on my throat, hear me out: There have been several significant financial events since then: the European debt crisis, then Portugal(which is relatively small on a global scale), same with Ukraine and Venezuela, Russia(still going 5 years later), Brazil and those are just off the top of my head. What I'm trying to say is that financial crisis occur almost every year. Keeping your finances tidy is a good life advise but prophecies shouldn't be the motivation for it.
