No, Argentina and Brazil are very different. For example, Mercado Libre and other unicorns started im Argentina and are serving Latam. Brazil has a large population and local market to serve while Argentina has a relatively small population, lot of land, and needs to look outside to growth.
Not at all, Brazil doesn’t have +100% yearly inflation.
It’s so bad that the government started reporting weekly inflation trying to trick people to think because the number is smaller, there is less inflation.
I heard the same thing from a colleague from Brazil, I can imagine that after containing inflation there are many more problems left to solve that are probably not taken care of either in Brazil.
