It's quite easy. Hi from Argentina!

Now the inflation is only 3% mom, but 2 years ago it used to be 10% mom.

In the neighboring Germany during 1920s the inflation went into triple digits, if not more. Did it help Germany restore faster? In Zimbabwe about 30 years ago, the inflation figures were ridiculously high, and daily expenses required banknotes denominated in billions. Did that help? A few other things must be present to make money circulation go brrr in a beneficial way.
