I challenge you to show me some data to prove this. Not so long ago you could get hired with wet ink on your commercial ticket. I don't seem to recall a spike in aircraft mishaps. In contrast the accidents that I have seen are high time guys screwing the pooch. Now I am not saying that I want two 250 hour wonders flying my wife and daughter around but I am saying that it is case by case. Where I currently work we have a huge mix of backgrounds. I have flown with 15K hour military heavy guys that I wouldn't let take my 172 on a trip around the pattern and I have flown with some low time non-military guys who impressed me. Its the pilot not the logbook!
