"We will continue to slowly but surely self destruct..."‏

To become a doctor you must serve an internship followed by a residency.

To become a lawyer you must pass a very difficult exam called "The Bar." 

To become a politician you must be a U.S citizen and reside in the city or county you wish to run in for political office.
The other requirements; you need to be at least 18 years of age and not have any felony convictions on record. Many politician have passed the bar exam but not the one that takes any intellect, just the one that makes one woozy.

Until we raise the standard for those pursuing a political career we will continue to slowly but surely self destruct.
