Uh, there are plenty of news about people with "higher" levels of education messing up. Let's just pick local Canadian news - there was recently a doctor who was caught for sexually harassing his clients for years and another doctor who killed his own children. I guess you just don't pay attention to those news but choose to memorize everything about celebrities instead. Having an education does not guarantee that you know how to live your life. Every person is capable of doing something stupid with their lives, just that if it's a celebrity, it makes the news much easier. Availability heuristics is something people really should be careful of when making judgments about others.
