Yeah, DUI should disqualify you from ever driving professionally IMO. Anecdotal, sure, but my experience is that people who actually have a DUI are the ones that finally got caught after years.

Then again, the well to do people I know (or ones with a well to do family) with a DUI actually got their charge reduced to reckless driving by fighting it in court, so maybe there are as many false negatives as positives.
