Extremely violence ridden, I had guns pointed at me in more than once instance, and I witnessed firefights from my bedroom more than once too, in different cities (one firefight was even in a expensive "safe" neighbourhood, what happened is that a dumb guy tried to steal the car of a celebrity private security)
Also, really bad environment to do business, we frequently get scored very low on "ease to do business" index, there is excessive bureaucracy, rules that change randomly (on average the country enacts 18 new laws per day, most of them related to taxes, subsidies, and so on...), excessive corruption...
Also the average brazillian is usually very, very treacherous, people are always warm up front, but quick to stab you in the back, this particular reason is one that I want to change my citizenship (I don't think the average brazillian deserves my life to defend them in case a war happen)
And there are also a mass of other problems summed (for example, trying to homeschool your children here is a felony, jail and all included, also the Gini coefficient is severely absurd, the top 0.1% get more money than their peers in many other developed countries, while the top 5% get less than US minimum wage, probably thanks to banks charging 70%/yr of interest, and credit card companies charging 250%/yr, making finance be wildly profitable, and anything else not so much)
The how! It is one of the reasons I did not left yet, I have no idea.
Most countries won't accept Brazillians wanting to go there legally permanently (probably because the havock that illegal brazillians spread around the world :/) with few exceptions (ie: have specific degrees in case of Canada, or be married to a local, that sort of stuff).
Also, although some of our cities (like Recife) kill people faster than some war zones (Recife body count for example rises faster than Iraq body count), noone will grant refugee status to a brazillian (specially, because it would cause a political fallout of some government admiting that Brazil has civil war, and the government here is trying hard to avoid that status, despite having the Army and Navy being in active duty in Rio de Janeiro and fighting people that are armed with military grade weapons, like bazookas and anti-air cannons)
And my assets are negative, this is a big no-no for many countries (like US, that don't allow entry of people with negative assets even as tourists, because negative assets means they having nothing to lose, and much to gain by overstaying their visas).
I have some crazy student debts here, and moving money in or out of here is not much simple, also it has some other implications... I am basically forced to stay until I pay those debts, unless someone offer me some REALLY good job elsewhere (REALLY good in the sense, that wage - cost of living is significant... although I currently earn 15k usd, a 80k usd job in SV is not much profitable for example...)
I really want to leave, but I cannot yet.
