What's really funny is that he thinks that a salesman's function cannot be replaced by automation or outsourcing. He is one of the lucky ones who happened to grow up during a time of great economic opportunity where a person with next to no education could get a great job, earn a six figure salary, and live in a 5000 sq foot house. This used to be possible, but is extremely unlikely nowadays. His hubris is such that he thinks all of his success is of his own hands, and doesn't understand that the world has moved on. He didn't need a college education with 35k debt to get a decent job, so no one else needs it. They are just lazy, which is why they are working at McDonalds trying to survive until they can get a start in life (where they will probably earn closer to 45k/year than the six figures he got).
But when someone looks at a salesman's job, what part of it actually requires the human presence? Describing the product? Nowadays people can buy almost anything online, and if there's a question on the product, just email 'John' who works from India and he'll happily assist you while earning $3.50/hr. Is the salesman responsible for haggling for the 'best price'? As Amazon has demonstrated, a product's pricing is a result of supply and demand. It can easily be automated, or set by the original producer. Perhaps marketing is the salesman's special skill? After all, sales involves informing people about opportunities, and convincing them they should do business with you. How else could a potential client know about your excellent customer service? It certainly is too bad that there's no way for people to read reviews about companies to decide whether they should do business with them. In fact, the best reviews might be from previous clients! Customer reviews...what an idea....
The truth is 'sales' is being reduced down to a simple transaction management job nowadays. In fact, the most value that a salesman can bring to a business is by upselling a client. Kind of like "would you like fries with that?". So don't begrudge the salesmen their opinions, their 'path to advancement'. After all, the world isn't quite as fair to the 18 year old with no college nowadays.
