Yeah, I remember getting 12% on a CD. Ah, the Carter days! Malaise out the ying yang.
I never could convince my then-70 year old Father in Law that 12% CD was really a money loser because inflation was roaring at 15%.
I was selling tax leveraged leases,in the late 70s, early 80s and the interest rates were any where from 15-25% APR and I had to get money on one deal from the Banc of Caracas, {we had to check it for white powder:).
