Everyone has a mix of: Debts, money they've loaned to others, amount of assets owned, and amount of dollars owned and wages (recurring income in dollars).
So, inflation is most harmful to wage earners with few assets - and most helpful to non-wage earners with many assets.
Increasing wealth disparity between workers (most people) and those who own the most assets. Those who own large amounts of assets largely don't own dollars - they own real estate, securities, etc..
The bank issue is a strawman - simply a matter of SVB (and others) making bad interest rate bets and losing.
