Free idea for anyone who wants it:

True crime podcast but instead of murders etc. it's just a long string of white collar crime that no one has bothered prosecuting.

Wage theft
Cooking books by doing layoffs
Cooking books by canning projects that could earn back their cost
Paying no tax by claiming your business is based in some random location with low-to-no effective tax rate

You could keep a podcast filled for years with illegal union busting.
