Your reasoning is intuitive, but I'm afraid you're wrong to some extent.

It's true that it's not an isolated case and PART of the society may be susceptible to pay or receive bribes, but according to a Brazilian historian, Marco Antonio Villa, PhD (https://en.wikipedia.org/wiki/Marco_Antonio_Villa), when Brazil was nominated as independent by Dom Pedro I, there was no corruption cases. The few cases that happened afterwards were severity punished. It's not clear exactly, however, when corruption was installed between that time and today. Now Brazil is going through a transformation. Corrupts are being caught, or at least giving satisfaction to prosecutors. The federal police is doing a wonderful job with many operations to uncover / dismantle white collar crime. Pushing forward this momentum will lead to a new country. And it is happening as I can see very close. You are just seeing many news in this regard because many cases got uncovered at once, so don't take the wrong idea. Your country or any other country have corruption or nefarious things going on that are only discovered in the future. That's all.
