Costs are not going down other than maybe a short blip. Recent increases were driven by an increased money supply, which was a response to covid. Covid will go away, supply chains will return to normal, but the money is here to stay. Inflation is a design feature of the world economy. Trillions of units in fiat currency were inserted into the world economy. Adding more money to the economy is like increasing the point value for your favorite sport (ie. touchdown is now 12 points, hockey goal is now 2 points, etc.) game scores would double, but it would represent the same amount of scoring. The same is true with money. One unit of labor, oil, housing, etc is just scored higher because we have doubled the amount of scoring units available (dollars, euros, pounds, etc). Housing will still cost 25-35% of the averages person's labor, a tank of gas will still equate to a couple hours of labor, food will still cost x units of labor. The only thing changing is the value on a scoring system. A unit of labor now costs employers more, a unit of housing costs more, a unit of fuel costs more. It isn't instant, linear or equal across all of the monetary scored items, which is why understanding inflation and positioning your assets to take advantage of it is how you transfer wealth.
Spend a few minutes reading about the following
-FDR gold standard 1933
-Breton Woods 1946
-Nixon gold standard 1971
Federal governments and central banks, entities with the most power over money, have an inflationary bias. Prices are not going down
*I have a strong bias because I make money from inflation, so DYODD and form your own opinion.
