In short:
Milei took 5% of deficit in Treasury and returned surplus in the first month.
Also took 10% of deficit in BCRA and neutralized in 6 months.

Milei taken 200% inflation, growing at 1% PER DAY during the first day and decelerated until 30% ANUAL for now.

Milei taken 55% of poverty and now it is 30% and decreasing.

Milei eliminated "PIQUETES" that, in short, are mafias that cut the roads to blackmail government.
He also reduced national public employment from 343k to 285k.
There is much more, but this is what I remember right now.
