We need better Inspectors Generals, Monitors, etc. to fight ripoffs of federal programs

The history of federal programs is one of unending, rip offs of huge amounts to dollars.  Here's a recent example.  I guess you could say this disgusting particular example is one  of a "rags-to-riches, "America is the land of opportunity" stories
Certainly, Congress must know that million-dollar ripoffs are SOP.  Why can't the write legislation or do something to deal with this problem.  Of course many agencies have "inspector generals."  Why can't they stop it.  First, many are political hacks who don' care.  Second, some  IG's are part of the problem.  See this example.  Although cleared of some of the charges, it's obvious his focus was not on his job.  Looks like he was too busy, among other things, of using agency resources to help he and his wife obtain graduate degrees. 

IG's cannot work unless we stop giving out these jobs are patronage for political hacks.  I don't know what the answer is, but perhaps some independent commission, composed of the high quality, knowledgeable people are of the highest quality make sure they appoint IG's with similar qualifications.
