I’m not going to dispute that either way, like I mentioned I know people that charge that much.
BUT
This guy isn’t starting a company, he’s working fewer hours at the same employer, he doesn’t have an office to pay for, and websites own survey doesn’t support the information being given.
If he was moving on to a new employer, and could take a risk of being unemployed for a period of time then you’re free to raise your price. But this guy has a family. He’s working at the same spot. Suddenly he cost x3? If I was the employer and that was the offer on the table I would let him go.
And I do know what goes into it, that’s why I opened up on it.
