The only way to meet the demand of the masses without inflation is increasing supply without increasing the marginal cost of the extra supply. These days, that's mostly driven by technological progress and aggressively pursuing efficiency. The primary driver of inflation is the human desire to procreate and improve their living conditions; not to say that's necessarily bad, but it imposes a constraint that can't be resolved by the rhetoric of rich vs poor people. While I agree economists seem to be too obtuse to realise the hypocrisy of increasing unemployment to reduce inflation, a primary issue is that we as a society haven't figured out how to control consumption in a way that makes everyone happy.
