There is nothing government can do to directly control prices, much less force them from going up given the deep structural problems.
There are ways to mitigate against the problem, or at least minimizing them. You can have a look at how Javier Milei did it in Argentina. He took the problem of massive hyperinflation and converted it to low inflation in a year. His is a case study.
The answer is:
end debt creation by dramatic spending cuts,
curb the actions of the central bank,
and inspire economic growth through deregulation and agency elimination.
That’s three steps.
