Congressional positions are not intended to be career positions or long term benefits generators. This is similar to the position of the presidency. They should be limited through Constitutional amendment expeditiously.No limits mean promotion of corruption and resemblance of dictatorship. In true democracies there always shall be changing of guards to eliminate complacency and becoming too familiar and overconfident in the position of power, which is very addictive and evil. Only integrity allowed the Constitutional amendment to limit the Presidency's term in office, and only integrity will do the same for the Congressional positions; this remains to be seen!
