My biggest all-at-one-time screwing came at the hands of a man that went on to become a representative in Oregon. Go figure, a dishonest politician. $32,000.
Other than that, my mortgage company has done a very thorough job screwing me on my home loan. No lube, no kiss, no nothing, just a good solid screwing. Any time I interact with them they seem insulted that I'm not enjoying it.
If I was ever elected to office, I would run hard at insurance companies and mortgage lenders and try to get some advantages back for the little man.
