Think of it like a see saw on the playground. on one side you have all of the dollars in circulation. On the other side is everything of value, goods and services that have real value.
They are balancing each other out.
When money is printed and added to circulation then it naturally tries to balance. So everything of real value over time rises in dollar value to match the.dollars in circulation.
The dollars are devalued because it takes more of them to buy something with real value than it did before the new dollars were added.
What it means to us when they added 20% more dollars to the economy during the covid scam, is the 1000 dollars we had in our savings account. Only buys 800 dollars worth of stuff now. The SOBs stole 20% of our work and savings.
