I say because the differences between % of income for cost (not however much you want to spend) of living become less in a deflationary environment.

"There are several points that could be made to refute the claim that a deflationary currency disproportionately benefits the rich while an inflationary currency disproportionately affects the rich:
  1. While it is true that the cost of living may be lower in a deflationary environment, this does not necessarily translate into a higher rate of wealth accumulation for the rich. In fact, deflation can be harmful to the economy as a whole, leading to lower levels of economic activity and reduced wealth for all individuals, including the rich.
  2. The idea that the rich are more affected by inflation is not necessarily true. While it is true that the rich may have more wealth to inflate, they also have more resources and flexibility to protect their wealth and adjust to changes in the economic environment. For example, the rich may be able to invest in assets that are less affected by inflation, such as real estate or gold, or they may be able to hedge their investments through the use of financial instruments.
  3. It is not necessarily the case that an inflationary currency disproportionately affects the poor. In fact, in some cases, an increase in the money supply can lead to increased economic activity and higher levels of employment, which can benefit those with lower incomes.
  4. The relationship between wealth and inflation is complex and depends on a variety of factors. It is not accurate to make a blanket statement about the effects of deflation or inflation on the rich or the poor without considering the specific context in which these phenomena occur."
