One of the core competencies of popular mainstream economists is their ability to command attention from either their peers or the public at large. There are, of course different distribution functions for both groups (something Krugman noticed) but the point is that a vast majority of academic and popular research is devoted to bolstering the status quo.
This tradition is as old as humanity. How else to get noticed by potential patrons? Cardinal Richelieu was more subtle when he wrote "A defense of the principal of the catholic faith" directly after the French coup of Louis the 13th which marked his ascension. The formula remains the same: offer clever arguments that absolve potential patrons in hopes of a sinecure. Apologetics remains the most furtive grounds for "philosophy" and it's offspring Political Economy.
