I want to second the sentiment that national investment supports achievement like this. IMPA has been very important for Brazilian mathematics, bringing people from across the world to Brazil to do high-level research. This means that some Brazilians who don't have have the opportunity or desire to move to Germany or California or Korea can work with and learn from amazing mathematicians who come to them, in Brazil. Since 1990, at least one Fields Medal winner has worked in France -- until this year. France has a culture of supporting mathematics and mathematicians. It has its quirks and difficulties, but national support for research has played an important role.
