Is Ethics is a personal affair and not a public debatable matter?

Is Ethics is a personal affair and not a public debatable matter?
Since the fall of the Enron corporation (known for blatant ethical violations of running the Fortune 500 company into the ground), we have heard a lot about ethical conduct.

Ethics are now being discussed more in college and even grammer school of doing the right thing and acting accordingly. More people today take ethics as a personal affair because of past presidences and the results of what happens if you do act unethical.

If you do act unethical, it is more of the judge character. Reviewing the corporate structure today, I think more people look upon it as a personal affair and it does not enter public debate until something unethical happens. =)
