Why no discussion of Tammany Hall and Minnesota corruption?

It is interesting and odd to me that, with the burgeoning reports of education, health, homeless, and other NGO corruption emerging first in Minnesota, then California, then Ohio, and now elsewhere, I have seen no accounts which reference or allude to our earlier brush with comprehensive immigrant based corruption - the infamous Tammany Hall.  

From Who Stole the People’s Money? – Do Tell highlighting the impact of cartoonist Thomas Nast on the illumination of Tammany Hall corruption.

The “Big Four” Ring members — Bill Tweed, Peter Sweeny, Oakey Hall and Richard Connolly — all belonged to Tammany, with Tweed as Grand Sachem (chief) from 1863 until his downfall in late 1871. Dignified John Hoffman served as frontman, first as Mayor and then as Governor.

Tweed confessed shortly before he died in prison in 1878. Asked to define “Ring,” he responded: “A combination of men to do any improper thing.” Nast often used “Tammany” and “the Ring” interchangeably.

Other crooked Tammany/Ring members included judges, law enforcement officers, city contractors, auditors, book-keepers, and token Republicans. They milked the city for somewhere between $30 and $200 million. (Perhaps as much as $4 billion in today’s dollars).

The Ring had multiple income sources, almost all of them illegitimate. While taxes were the most prominent, bond issues were important and kickbacks from employees played a role. (Even a poor teacher had to pay $75 of her $300 annual salary to keep her job.)

The parallels with Minnesota are everywhere. 

Urban corruption

Blatancy

Immigrant group origins

Democratic party

Siphoning off tax revenues

Staggering size and pervasiveness of the corruption

Elected officials involved

Exposure by third-parties (independent journalists and cartoonists)

Co-dependency between the corruptors and the political establishment

If one were to make the argument that the corporate legacy mainstream media are the propaganda branch of the Democratic Party, then it would make sense that no one would want to draw the parallel.  But since I have not seen any allusion in the independent press either, I fear it might simply be historical ignorance.  Hopefully someone will draw out the parallels soon.

Kind of distressing that 150 years later we are suffering similar symptoms as before.  

Maybe we can learning something this time about more permanently excising institutional corruption.
