Good Employees

Is there just a shortage of good employees/hard workers out there? I mean, when did it become okay to show up for a job interview in jeans or a t-shirt or a baseball hat? When did "that isn't my job" become an acceptable thing to say to your boss? I have witnessed all of these thing lately. I guess I was just lucky to have parents that taught me common sense and instilled a good work ethic into me. Seems these days common sense is an endangered trait, if not an extinct one. So sad, so frustrating, so ridiculous that we accept this behaviour and the standards just keep on dropping.
