That chart kind of illustrates a key difference between the current inflationary period, with the inflation of the early 80s. The massive gap between the truth (real inflation,) and the lies (official inflation.)
In the 80s you could earn 10-18% interest for doing nothing.
Today, we'll be lucky if can get 6-10% (when we should be at 12-20% right now.)
Plus, jobs are now being lost, food cost is inflating, energy is being squeezed (making food go higher still,) consumer confidence is wavering going into Fall & Winter, the Fed is probably going to hike rates 4 more times before the election, and the election means nothing is going to change until possibly Summer of '25...
And through it all, the average American's checking & savings account is still only earning 0.1% to 0.17% monthly interest.
