Probably the entire adult population gets away with hundreds of offenses per annum on average (judging by the total amount on the books).
Even the most law abiding and most humble decile of Brazilian adults probably still get away with dozens of offenses per annum. That nobody cares to enforce at all.
Selective enforcement allows those in power to corruptly select who to prosecute. Even though many (perhaps most) "have-nots" will "get away with it", selective enforcement disproportionately impacts the "have-nots" as they have no leverage.
