Does a high inflation rate make producers better or worse off?

High inflation (meaning high prices) is bad for everyone. Consumers and producers alike. Producers still have to consume so whatever profit they turn goes to paying the premiums on their other consumables. Consumers become more thrifty in the face of higher prices and become more cost-conscious. Let's say, Shirley and Rob are able to produce rice and beans for a little less than Rita and Bob. With high inflation and tight consumer pockets, consumers behavior will predictably go in the direction of cheaper goods, which will hurt Rita and Bob.

Your prices on rice and beans don't tell me much, because there are no indicators on cost and leave out a whole range of variables that are equally important, such as competitors, supply and demand, interest rates, etc.

But anytime high inflation spikes occur, it is generally bad for all in the economy.

In this simple example, all that matters is relative prices. If the product you sell becomes more expensive you're richer, if the price of the product you consume increases, you're poorer. You have to calculate both effects to find the net effect.
