This is a country with obscenely high interest rates, currently at over 14% per year. It's just ridiculous. And inflation is still hovering between 4% to 5% per year, just under pandemic levels. The solution is for the government to stop spending money. They don't want to do that, they want to increase taxes instead. As a result, we're at record breaking taxation levels, last year Brazil achieved its highest tax revenue since 1995.
The current administration spent the last two years crying about the central bank's high interest rates. I can't even fathom what'd happen to this country if they got what they wanted. Mercifully, central bank has some degree of autonomy from their stupidity. After a couple years they get to appoint the head of the central bank. It turned out even their own guy wasn't stupid enough to lower the rates.
I think the only reason they haven't taxed Pix yet is the fact Pix is too popular already. I have no doubt they're still gonna manage to increase revenue by cross referencing Pix data for tax purposes.
