The point of this question is to get a sense of what is it like to earn more than needed for consumption in a middle income, high inflation economy.
Specifically consider large middle income South American economies that have historically experienced high inflation such as Argentina (per capita GDP 10K USD, PPP more than double that) or Brazil (per capita GDP 7K USD, PPP more than double that). The chart shows that even in a high inflation economy like Argentina a large part of GDP can be saved. This is a chart of domestic savings which is not the same as household savings because it probably includes corporate and government savings. It would be good to determine how much households save and specifically the households that do not have a household member working for a government. In other words, I am interested in the savings of people who are not entitled to the kind of pension paid to former government workers.
Specifically what are the characteristics of private sector workers' household savings? DB means defined benefit savings and DC means defined contribution savings. Is it common for companies to offer DC plans in these economies? Are workers allowed to direct contributions to DC plans in the way of controlling the mix of equity, bonds, and guaranteed investments, and the currency denomination of those investments? For example suppose a household can save 15% of income. Would this household be able to put the entire amount into a U.S. Treasury bond fund or U.S. large cap equity fund or a mix of these? How much of private sector workers' household income is being saved? How much of this private sector workers' saving is in land and buildings?
To supply some context, inflation in Argentina in recent years is graphed here...
