I am not advocating tax evasion. I think, US for example, is a great place to do business, as opposed to Greece, because the letter of the law is followed and the rules are clear to everyone. I am just saying that the Greek government was so inefficient and the public sector so bloated, that in some sense tax evasion was helping put people's money at more efficient uses.
Such as building their own private businesses and employing other people in the private sector.
For example, it is much more beneficial to the country to build, say a new hotel (as this is Greece's biggest industry), instead of wasting the money on more public-railroad-type of money wasting businesses.
