Last week’s bribery charges against 70 New York City Housing Authority employees are just the latest in a long list of scandals by low- and mid-level public workers in New York who abuse their power over their public mini-fiefdoms.

On Tuesday, the Manhattan US attorney accused the employees of skimming $2 million in bribes in connection with NYCHA repair contracts worth less than $10,000 apiece but that added up to a whopping $250 million.

It was the largest number of Justice Department bribery charges ever in a single day.

The bribes averaged about $28,000 per worker, though some managers made far more. Nirmal Lorick hauled in $153,000 from $1.3 million in contracts, prosecutors say; Juan Mercado scored $314,300 off $1.8 million in contracts.

NYCHA’s $78 billion repair backlog, on top of ongoing maintenance needs at its 2,411 buildings, makes it ripe for corruption.

And corruption has long plagued the agency, from the lowest-level workers right up to the top:

Even small-time corruption adds up. Residents suffer, as stolen money could otherwise be used for repairs and upgrades.

But such skimming, deception, and self-dealing have been pervasive not only at NYCHA but throughout city government:

Note, too, that this federal investigation was built on one by the city Department of Investigation five years back, duly flagged at the time by the left-leaning site The City and in these pages.

Which suggests zero interest in the rest of the city government in exposing such corruption.

It’s as if insiders’ general attitude is that there’s really nothing wrong with abusing the public trust to line your own pockets — even though the actual victims are usually the city’s most vulnerable.

As far as NYCHA goes, housing expert Howard Husock argues that privatizing management is the best way to limit corruption.

Hmm: City insiders generally treat “privatization” as a dirty word, along with “merit pay,” “productivity increases” and anything else that might make the government deliver more bang to the public for its bucks.

Makes you wonder who’s really working for whom.
