Paying for Financial Advice

A delightful quote from Warren Buffett is "Don't ask the barber whether you need a haircut."
He is referring to the fact that financial advisers are only paid if the deal they are advising on is completed, so they are hardly going to raise concerns about the deal.
It's rather the same with pest and building inspections for houses. Some say the vendor should provide the report, to save buyers from the cost of an inspection for a house they decide not to buy. But how can the buyer know the validity of the inspection report? If the house is, say, riddled with termites, the vendor could keep having surveys done until an inspector doesn't notice, and offer that report to buyers. Indeed, word would soon go round as to which inspectors could be relied on to give favourable reports, and inspectors who were too honest would find themselves not being invited to work. The present system encourages inspectors to be thorough and honest, which surely is what the buyer needs.
