> As a college student I worked as an office temp at the hq of an midsized areospace company. They had a Treasurer, Asst Treasurer and clerk. Part of my job every morning was to get the short term deposit rates from a list of banks whom they did business with. They then would place their excess cash with a number of those banks. Wouldn't it have been more useful if that job simply didn't have to exist, and they could just deal with one bank, and then that extra capital could have gone to something more useful? Change the game so the risk is being managed in a way that doesn't require every single company to wastefully play financial hopscotch so they can instead focus on doing what they do best.

Do you think that was a good use of your time? Maybe it would be better if depositors didn’t have to worry about such things. What would be lost if all that busywork just went away?

Did you explicitly open the new account at a new bank? Because if you just opened a new bank account at the same bank you don't actually get any extra protection.
