It actually takes a smart person to sell you a faulty services so you can say their aren't smart, you actually should not blame the business man alone if you get any faulty goods but the manufacturer of those substandard goods and also the government that lets then keep running. Every country should have a body or institution that are in charge of making sure that substandard goods aren't in the market.

I don't know where you manufacture your statistics but it is not easy to do business now successfully especially now that the global economy is not as it use to be and many people are actually doing the same business or very similar.
