We have become like the former Soviet Union with much of the economy being a black market that hides under the radar.
I believe that the family earned this money 'honestly' with the only caveat being that they earned it in such a way that it might not have been as taxed or regulated as the government would have liked.
In the long run it would be better if people fought against the government for lower taxes and less regulation, but individuals who have to make a living and provide for their families can't wait until the congress pulls its collective head out of its posterior.
Their only option is to work off the books.
I honestly don’t know what to believe about it, frankly. The story as reported just seems suspicious to me. The very last place I would go is to eat out and leave a pouch with $32,000 in it in a restaurant.
