How exactly you ask?  They exactly failed to exercise their fiduciary responsibility which made us vulnerable to the variables you mention.  While they didn't bring about low oil prices they sure as h*ll knew that prices had collapsed before and that they were dealing with a non-renewable resource. Decreasing production of any non-renewable within a given area is inevitable over time. No excuse especially after their first lesson in the 80s. 

P.S. As to it being my fault,  I did not vote for any legislative incumbent, did you?
