You have it reversed. Currency inflation leads to unfair distribution because the value of financial assets grows faster than the real economy (it inflates).

You have it reversed. Currency inflation leads to unfair distribution because the value of financial assets grows faster than the real economy (it inflates). Currency deflation benefits the poorer. As technology and productivity grow, it costs less to produce goods, so their prices should decrease. The currency hoarding behavior that you describe is no different than today’s financial investment. It is trivially easy to avoid the effects of inflation by investing - if you have assets to invest, that is. But if you live month to month, you get screwed by inflation, because your salary is sticky as prices rise.
