I was there during Menem's hyperinflation at the end of the 80s, beginning of the 90s.

All the stores closed for a few days after Christmas 1989--they would not open because they didn't know what price to charge, because inflation was blasting out of control.

the WIN button (whip inflation now). Yah, that's the ticket.

I think it's a good idea sometimes, and part of a good economic policy.

Were they offered supply and wage price protection as well? Perhaps subsidies in hardship cases?

Sounds good for consumers as long as the supply chain remains unaffected.
