I've never run a large company but I feel like it wouldn't be feasible when you have transactions routinely over 250k, like how I'd imagine most of these companies would be with their payroll.

I think the solution to that is placing predence on the bank selection mechanism. You could audit banks' lending positions and make risk adjusted based decisions.

Lots of people have way more than that due to retirement accounts (which sometimes need more liquidity or people want to get out of the market so they have more cash on hand). Or even if you have a down payment on a house in most of the coastal states. 250k in the bank is not much money these days.

I just don’t understand this attitude. It’s 250k. We’re not talking about all that much money. Why do you think people with 250k should have extra knowledge or access to special advisers?

I think you're out of touch with how much money Americans have in savings

Vs say, 1k in savings or 10k in savings, somebody with >250k in savings certainly can pay some form of fiduciary

Well, it's not just individuals with their savings. It's businesses, too.
