It's not a feedback cycle. Inflation is the increase in money existing. Paying higher salaries do not increase the amount of money existing, as that money is taken from somewhere. Raising prices do not increase the amount of money existing. Only the money creators can increase the amount of money existing. Money is created by banks and governments in symbiosis.
Increased prices of labour or products is always a consequence of inflation and never the cause of inflation.
This is conflating "money", which you seem to take colloquially to be a finite quantity of "stuff", with "money supply". Inflation is the result of an increase in the latter, but emphatically not the former. In fact money supply grows and shrinks for all sorts of reasons that have nothing to do with things being created or destroyed.
And to my point upthread: the factors that result in changes in the money supply are themselves subject to influence by lots of things, including stuff like the rate of inflation. It is absolutely, 100%, a feedback network.
