This assumes you know that they are deceiving you. If the company is successfully deceiving you, then you will not know it.
99% of companies I interact with have no way to deceive me in any significant way, and the few that do (e.g. maybe a bank, insurance, or other financial companies) I double check on and I take action to mitigate the risks.
Moreover, companies who commit fraud eventually get caught and their people go to jail.
That is all part of a free market system, not a command-style, over-regulated Marxist one, which just hurts people in the long run.
People who advocate that kind of system are serious evil.
Which is why all the bank executives are currently in jail? (Contrast DOJ enforcement after the latest financial blowup to their conduct after the S&L crisis).
