I've always thought that after one drunk driving offence you get a huge fine and a good long license suspension, but eventually allowed to drive again. After a second offence your license is gone for good, no questions, no chance to ever get it back again. (and this in addition to any other fines, charges etc. that may be imposed)

Anyone can make a mistake once, and should be allowed to atone for it. Do it again and you're done for good.
