The decline in what we expect of our leaders has been going on my entire life and the contrast between 20 years ago and the present is stark.
In 1998 Meriwether and the rest of LTCM nearly crashed the economy, needed the Fed to get involved, and they were personally ruined, guy never opened a ten thousand dollar bottle of wine again and probably never had anything again. Shortly thereafter, Jeff Skilling took out offices in 9 cities and pension plans all over the country with shady accounting. 24 years in prison (reduced later to 14). Ebbers/Worldcom 2002: died in prison.
By 2008? Zero prosecutions. Bonuses the next year.
Around the same time Clinton got caught lying about chasing (consenting and of age) skirt in the Office: nearly ended his presidency, definitely ended his policy agenda, real consequences and he caught a shooting star to avoid far worse. The public was not going to accept it, Congress was not going to let it slide on either side of the aisle. Today? Something like that barely makes the press. You have to be accused of sex trafficking to even get an investigation started and everyone will probably walk.
The idea that this became uniquely bad in January, or even 2016 is demonstrably untrue. At some time in the last 30 years we started accepting leadership who are dishonest, nakedly self-interested, lie without consequences, enrich themselves via extraction rather than value creation, collude with no oversight, and sell out the public.
This is a completely bipartisan consensus on these norms. Speaking for myself, I think Trump represents a new low, but not by much, he's just the next increment in what history will probably call the Altman Era if his ascent to arbitrary power on zero substance continues on it's current trajectory.
