"I would argue that crappy developers are more productive 'initially' but in the longer term may end up with unmanageable code bases that will slow them down."

I agree that their productivity will suffer in the long term (if their business lasts that long). However, my guess is that even the initial cut of the code will take longer to get right. Hastily-written crappy code may be faster to write, but it's probably going to take significantly longer to debug than clean, refactored code. And quick and dirty fixes on top of dirty code can frequently break more things than they fix.
