I just wonder where they got the idea, what the principle is behind it, where they got the money to carry it out. Could it be public money, so the public is turning in something of value (perhaps) in return for their own money. This might just be the same double scam that the tax system anywhere might be called since money is not taxed just once, but multiple times. So joe public takes it in the ear because he is so stupid. Ah well, let the buyer beware.
Tax rate is REALLY high in Brazil, especially for anything you bring there from another country. Something like 78% on foreign cars. The gov. has money, they just never use it to bring plumbing and elec. to the poor people who live in the shacks all over the place. They do like to build expensive memorial statues. Maybe they plan to melt the old guns down for more memorials.
