types of instabilities
Misanthropes thrive on physical instabilities. Catastrophic events of all sorts are welcome. If there are no such events happening now, then the misanthropes will forecast one to happen sometime soon.
Intellectuals thrive on political instabilities. Popular uprisings, wars and massacres are all welcome. If such events no longer occurred, then intellectuals would switch careers and become historians.
Traders thrive on economic instabilities. Any event that introduces volatility into the markets is welcome. Even if there is no such event happening now, sooner or later the susceptibility of traders to herd behavior will create one spontaneously.
