In my country, and for at least dozens of years, many people evade taxes, especially in some professional groups. Tax evasion is recognized as a common behavior, even if accepted only in private (or at least not too public) conversations. There are some rough calculations about how big tax evasion is. This has had many consequences: a) Tax rates are a bit higher than they would be if there were no evasion; b) Unions agree on salaries knowing that their members will have to pay for these hight tax rates or, on the contrary, that they will be able to evade taxes; c) Professionals charge for their services knowing that they will be able to evade taxes; d) Some professionals and corporations evade taxes because, if they wouldn't, they wouldn't be able to compete with low prices; e) People who do not evade taxes, although they could, know that many other people do, and they do not evade either because they think that is the right thing to do, or because they are affraid that they are caught. Do you think that this is a moral reason to evade taxes, so that one pays more or less only what one would pay if there were no tax evasion and tax rates were lower? I understand that some of my descriptions may not be very accurate, but please answer as if they were.
