They support it, encourage it and benefit from it.
Quite.
The battle between parties is a 20th Century relic.
The current and future struggle will be between the political class and...everyone else. The political class will occasionally conscript a temporary army - gays, illegals, college kids dabbling in Marxism - when it suits their needs but will close ranks quickly. Once in a great while an ‘expansion draft’ is held and another great lump like the TSA will be grafted on.
The political class have all the traits of organized crime - secrecy, evasion of accountability, mutual protection against outsiders, elimination of competition. Unlike criminals, however, they have the power of the law and when the law fails to support their actions or even contradicts those actions, the political class will do what they like anyway.
Visit modern DC and you will see Nova Roma. Do a loop in one of the eight or ten lanes of the Beltway and gaze upon the fortresses and temples, where private contractor is indistinguishable from public agency, where they are cocky enough to gild door handles, install huge fountains and maintain elaborate landscaping. Buildings bristle with security measures, because government of, by and for the people is a nice sentiment in 19th Century Gettysburg but they really don’t want any of those icky citizens visiting or knowing what’s going on.
The political class have drawn their lines of demarcation even in the smallest towns. Courthouses, schools, even the DMVs resemble Fort Knox with all manner of thinly-veiled threats posted against getting out of line (literally, in some cases).
Lois Lerner is the pallid, soulless face of the political class but merely the latest example of the ruthlessness with which they will protect themselves.
