Which is what happens when the government tries to tax productivity out of existence. I recall several decades ago reading that 30% of Italy's economy was underground. With oppressive economic policies, it's either that or go out of business.
When I have work done at my home it is not uncommon for the service provider to say, "If you pay with cash the bill will be reduced by 20%."

Ha...the Italians invented double book keeping...
and the Greeks invented triple book keeping...
one set of books for the business owner...
another set of books to show his spouse...sans "funny money" for gambling and mistress...
and the final set of books to show the tax inspector....
Some years ago there were very profitable computer/software companies in Greece that specialised in such systems.
