Locally I have found that they do this:

Corruption funnels that use the courts (keep in mind that judges give themselves immunity) to prosecute intentionally created swindles.

Example:

Public agency hands out taxpayer money to corrupt private businesses intentionally. The companies inevitably get sued for cause.

Due to lawsuits, courts take over the businesses using special masters and receivers in order to "recover" the money but it is actually funneled to judicial accounts/personal pockets. This pattern repeats over and over.

Notice that Christine Smith, an employee at RI Commerce, (a public agency that hands out taxpayer money) has Georgetown U. history degree yet her expertise is technology? And just happens to be married to a Fed judge in same state, William E Smith. What are the odds?

These judges are all buddies and enrich each other.

Favored lawyers are awarded huge payments, for example, another current RI Fed judge, Jack McConnell, had a case that was previously granted lawyer fees/award of $millions/monthly for years by now retired state judge M. Silverstein.
