For those who don't know their mythology and the reference, this was one of Hercules' seven tasks. The stables had not been mucked out for years. Hercules' solution? Divert a river to wash them out.
We need to see something similar. Flush out the professional politicians and replace them with truly local representatives. These elected (non partisan!) men and women would serve a single four-year term, then be retired. While elected, they would draw a competitive salary and have a fixed annual expense budget. (No need for auditing or unlimited spending!) They would also have a small, efficient professional civil service support staff. After a term out of office, the individual would be eligible to run again for a second term. No individual may serve more than two terms.
A committee would be elected from among those elected to replace what are now styled 'cabinet ministers'. This cabinet would elect, from among themselves, a national leader, currently termed 'prime minister'. Any proven malfeasance of any representative, in addition to any legal consequence, would bar them from holding public office again for life.
