There is no such thing as incremental ethics reform.

First and foremost, ethical reform means truth telling.

If it is alright for politicians and public servants to tell the truth
incrementally, then it is alright for you and I to tell the truth
incrementally.

So, if you ever find yourself in a court of law, and you are asked;

Do you promise to tell the truth, the whole truth, and nothing but the truth?

you may respond;

"I do, incrementally."
