I am not surprised that bank profits are very high.
Many banks are still paying their depositors 0.02% interest on their check and savings accounts and lending it out at 5 or 6% interest.
Apple has a deal with Goldman Sachs and pays 4.15% on my balance. I can wave my phone at most stores to pay. I still have an account at Chase, my local brick and mortar but rarely go there. I do most of those transactions electronically. Occasionally, I use the drive through ATM. All of my income streams are deposited automatically and when I receive a check I deposit it with my phone camera from home.
I do keep a stash of cash and precious metals for emergencies. The current system works well.
