> That's never true, countries changed extremely, also cultural-wise. If talking Germany the basic example is changing from a very militaristic society (far before the Nazis) to a rather pacifist society.

After suffering a massive defeat, losing millions of lives, and being occupied for decades.

Otherwise culture changes slowly, I won't waste my lifetime to see 5-10% improvements, you are totally free to move to Brazil and fix it for us since it seems to be an easy task for you.

> If talking corruption, my own country has progressively became far less corrupt over my lifetime

In mine it only got worse, religious nuts like Evangelicals only accumulated more power over my life there, in my almost 30 years living there progress outside of economical terms got stuck.

Corruption is only one issue, violence is another major one, macho-culture and sexism is yet another, religiousness in the form of Evangelicalism with tele-pastors only grew to become >50% of the population.

It's an absolute fantasy that me staying there for my next 30-50 years of life would've made any difference. I only have one life, I won't waste it at a place where I always felt like a fish out of water with no power to change it. My life won't be dedicated to politics and power plays to the point where I could have any meaningful impact, I'm just a normal person trying to live a decent life, not an agent of change, lol.

You are completely invited to move there and change it though.
