I have to agree with Glen Reynolds that this is an awesome quote, from a member of the teacher's union in Denver:
That’s your problem. You’re an entrepreneur, so you don’t work. You don’t know what work is until you get into an educational area.
Yep, some day I will have to stop loafing around and take on a brutal assistant principal job somewhere. All I have to worry about is that every dollar I own (and more) is invested in my business and could disappear at any time if I make a mistake. Thank God I don't have to sit around all day worrying whether the doctor that hands out no-questions-asked disability rulings will still be practicing when I am 45 and ready to retire.
I call this the "Dallas / Dynasty" perception of business, that businessmen just grab a phone call or two, go to a power lunch, and then head home to the mansion.
Update: Apparently this is a common misconception about entrepeneurs
The average number of working hours per week of a successful starting entrepreneur is seventy. This catches the typical American dreamer by surprise.
Nor do teachers spend all of their time at school in the classroom. In fact, teachers spend fewer hours actually instructing students than many recognize. Stanford's Terry Moe worked with data straight from the nation's largest teacher union's own data - and found that the average teacher in a department setting (that is, where students have different teachers for different subjects) was in the classroom for fewer than 3.9 hours out of the 7.3 hours at school each day.
With several hours set aside at school for course-planning and grading, it strains plausibility that on average teachers must spend more hours working at home than do other professionals.
Not to mention, of course, summer vacation, Christmas break, spring break, fall break.... Oh, and the fact that they have lifetime job security because in public schools they can't be fired for even the most egregious incompetance
