Yep, South Korea sent four ex-presidents to prison (three were pardoned, one is still in prison). It's not a perfect solution (obviously we'd prefer if we had presidents who didn't commit crimes), but I think it's a net positive. Surprisingly, when you throw an ex-president in jail, the society doesn't break down. The stock market barely even notices.
