The United States Constitution and all included Amendments do not grant Elected Officials a right to a pension for performing a public service of holding a Governmental elected position. Additionally, the legislatures that drafted and approved these bills also granted themselves short tenures to qualify for these Government pensions. There is zero justification for any elected official to not only receive a pension for serving the public, but then to be able to obtain a pension for only serving one term.
The simple solution is to first abolish the bills put into place by the politicians giving themselves tax payer dollars. Enact a simple IRA for Elected Officials whereby the Government matches the first 3% the employee contributes. This is in line with the private sector.
