"When Milei came into power," says Ian Vasquez, vice president for international studies at the Cato Institute, "there was 40 percent poverty rate…annual inflation of over 200 percent."
Monthly inflation at the start of his presidency was about 25 percent. Last month, prices rose 2.7 percent—still too much, but way down.
"When Milei lifted rent controls," says Vasquez, "the supply of apartments in Argentina tripled and their price fell by about half!"
Argentina still has big problems, like lots of poverty.
Poverty went from 43% to 53% according to this report. IIRC Milei attributed it to disruption and perhaps there's some lag when inflation declines like this. Personally, it's the one stat I'm watching before declaring his reforms a success.
