Given enough time and money and the correct choice of major, idiots have always been able to graduate.

While I agree that determined idiots always got through, with more barriers idiots were more likely to run out of the time, money and persistence to get through. And if they did, you could look at their choice of major to get a clue as to whether they were capable.

The problem today is that people with technical looking degrees like Computer Science cannot be expected to possess technical abilities or skills.
