There can never be another government with power again. Governments need managers who work for the people with very strictly defined limitations of authority that are just enough to accomplish the objectives of the people.
They should have zero immunity and not be allowed to make money on other ventures other than straight investments during tenure. Also strict conflict of interest laws with very severe penalties. Pay them more but do not allow them any income.
The lobby must be criminalized. Political parties criminalized. Campaign funding minimalized to bare minimum to publish your message.
This is not negotiable.
I will never respect the authority of any government not following this model again.
