This makes no sense. If you want to open a restaurant, you need to know the restaurant business well, not how to efficiently coordinate table serving.

Perhaps I'm a jerk, but I don't feel bad making fun of people who write dumb comments on Hacker News.

Or.

Perhaps I'm a jerk, but I don't feel bad when non-business people get take for a ride when hiring people to help them run the business side of their tech-startup. Why should I feel sorry for someone who feels that he can make a go at something that requires highly talented, seasoned workers who understand the details of how to run and grow a business?

Anyway:

Not everyone knows everything. If you are hiring someone because you're aware that you lack the skills to get something done, that's fine. That's why you hire experienced people. And when you hire them, you expect that they'll do a good job at what you're paying them for. Businesses require teams of talented people who can trust one another. Not everyone knows everything -- and if you think that everyone should just take advantage of each other, well, remind me to never hire you. Or work for you.

Perhaps I'm a jerk.

Keep in mind that this article is about hiring outsourced/contract/freelance labor, not future partners/members of a team.

It's more often the case that the hire isn't as good as he believes. Which is perfectly fine, because the person/"entrepreneur" that performed the hire is also still learning about the business.
