The interesting take to me is those could all apply to legal or accounting. These fields are also vital to a company above a certain size, yet partial or full outsourcing/contracting to an external cabinet is common.

At the end of the day it's a matter of trust ("you get what you pay for" feels weird to apply to Deloitte for instance. You absolutely get less than what you paid for and they get to pocket the most of it, you just don't care enough about the money to want to handle it yourself)
