Our future daughter in law and her parents and brother moved to the U.S. from Brazil about 20 years ago. Her father told me that one of the main reasons they did so, was because he knew that in Brazil, it was hard to get justice when you were wronged. He saw, from having spent time here in the U.S., visiting family, that people who robbed, assaulted, or murdered someone, would usually be caught and eventually punished. He believed his family would be safer here, so they emigrated. He and his wife have worked hard, starting a cleaning business. Both the kids went to college, Sarah graduating from Law School last year, and her brother going into Finance.
The Brazilian people are wonderful and I'm sure your son will be happy with his Brazilian wife. Brazil is also a great country. Unfortunately, it can't get rid of its corruption and this makes it a dangerous country to live in or to visit. During the period of the military dictatorship, it was safer, I think. The last 25 years have seen a steady increase in crime and lawlessness. The rich live in gated communities. Even the middle class are starting to live in gated communities. I've been there twice for extended visits and was thinking of going this summer, but I'm not so sure now. The crime problem is just too much of a worry.
