This line of thought is however used elsewhere by scammers ("the person bought it at that price so they must like it"), free market absolutists ("the market - the sum of supposedly infallible decisions - made me rich and made you poor") and leads to people playing World of Warcraft 24/7 ("it is my choice, how can you argue that"). Anecdotally I have received good advice from people and when I followed it, it changed things to the better.
