There are currently over 600 pilots (with airline experience) on the street in Brazil, this without counting the ones that are active outside Brazil.
GA aviation is not as big as you may think, it is very active in some regions, but overall especially fixed wings the market is very small. Most of the private jets sold most of the time just sit around, same thing for the many piper Meridian/Matrix/Seneca. The amount of hours they fly per year often does not allow for a full time pilot.
I fly in the Amazon basin, and there aren't really that many GAs aircrafts on Amazonica, compared to what we have here in this country the size of the state of Amapa.
I was once also very exited about Brazil.
