Entry-level salary for both senators and representatives begin at $174,000. It is said that last generation's Congress was the least productive and the current generation isn't looking very productive either so far.
In the private sector, employers have the ability to reduce pay of workers who are unproductive. This ability should be extended into the public sector, as well, allowing the taxpayers (the employers) to reduce the pay of unproductive congressional members--individually or as a whole. An online voting website should be created for this sole purpose.
Another option is to reduce the base pay to ~$100,000 and institute a bonus in which the taxpayers (the employers) vote on whether or not to give X amount, if any at all.
Moreover, rescind Congress' power to give itself raises.
