Every time a politician commits an offence the president/prime minister should go to prison?
Every time a pupil breaks the law, the principal of the school should go to prison?
I'd suggest the reason 'no on else seems to have learned' it is because it's a ridiculous and impractical idea. Should CEOs (etc) be punished if they knowingly aid and abet crime and/or cover it up? Sure, I think most people are on board with that.
