I would post it myself, but I need 81 upvotes to this post to get me there.
I gave my one. :-)
I keep 200% of my average spend between deposit periods in checking and move the rest to a 'holding' account that's a money market account (higher interest). If I need to contribute to my IRA, pay real estate taxes, make a large purchase, etc. I pull from here. I'll also use this money to make some investments that I consider liquid (i.e. have Apple now, just sold Tesla).
There's more to it, but this system works well for me. I had an issue when I first got married because my wife is a bit more of a...liberal spender than I am. I have it set to always payoff my credit card statement balance every month and was surprised a couple of times how somebody could reasonably spend that much in a short period of time. But then again, this is coming from a guy that drives a Honda Civic, spends a few hundred a month in food, exclusively wears ~$17 jeans, and loves $3.77 Costco lunches that include a slice of pizza, hot dog and a drink (awesome, right?).
You can always buy another one you rich motherfucker.
The problem in America represented by this poll aren't the ~40 people who upvoted >$150k but that the sheer majority have <$3000, like me. That is the problem, that sheer majority[1] of us have to live paycheck-to-paycheck and should a catastrophe happen, we'd be bankrupt.

I'm curious as to how many people actually keep 90% or more of their total liquid short-term assets in a bank. It seems like a basic rule of diversification of never keeping all your eggs in one basket, including the the bank.
Generally though there's things like Brokerage Accounts etc which offer higher levels of insurance (SIPC) and easy mechanisms to spread monies across several banks and account services (CDARS for CDs and MMAX for money market accounts).
At that point hopefully you have someone managing your money wisely to help navigate these kinds of things.
'Safe' stocks (utilities, etc), precious metals and real estate are all nominally safe investments as well.
If you would like to increase the interest received on your money, then holding a portfolio of value stocks or an index ETF will outperform your bank account by a large margin over time. This takes very little effort, but will suffer from the occasional (large) drawdown that you have to sit out or this strategy won't work.
If your primary objective is capital conservation then buying high quality debt of countries would be a good idea. Singapore or Switzerland are good candidates if you consider it a real possibility that the US could default on its obligations. Otherwise you could hold Treasury bills and roll them over once they mature or you could use an ETF like SHY that holds short-term Treasury bonds.
You could also buy precious metals if you are convinced that civilisation is going to end in the foreseeable future. Drawbacks are fluctuating prices and the complete lack of interest payments.
I'm unclear if you're asking how many people keep 90% or more of their total liquid short-term assets in a bank or not.
I'd expect most people keep most their short-term liquid assets in a bank since this is usually just their cash on hand. But this is not "all their eggs" considering their long-term non-liquid assets are probably tied up in some sort of retirement vehicles (which are hopefully diversified), and their homes.
Have fun retiring without 401K/IRA.
Also, if your sentiments were generalised across the population it wouldn't just be the banks suffering. We'd have a massive credit crunch. Regular, honest people wouldn't be unable to get mortgages or business loans.
People with that experience might sell their assets, hold the money in their account until everything has settled, and then move forward.
Also folks who sell stock options often have big tax bills to pay. But rather than slosh that money into and out of something that pays .5% interest they are just leaving it in their account until sending it to the IRS on 4/15.
The bottom line is it is that the answers look different from two sides of the bank balance :-)
I don't think I have ever left that much money in my account for any length of time, but I do recall the CEO of a company I helped get started put the $1.5M series A check into their account while waiting to transfer it over to the newly established corporate accounts. He joked the bank staff treated him very well after that :-).
And while mine wasn't anywhere near $1.5M, I did notice a slight glimmer in the eye of the teller that brought up my account balance. Before we could even begin the transaction I came in to do, she asked me if I'd thought about switching to a different account type because of that balance. I had to cut her off and tell her that today's transaction would be a large cashiers check because I had just bought a house. :)
ps. I'm old.
Today: Checking: ~$2400 Savings: ~$250 (I'm just getting started and paying off major student loans ~$120,000 to go...)
Tomorrow: Checking: $5200 Savings: $325

I usually just say that I'm frugal, but one has to be when all that comes in, goes out.
For example, home-equity line of credit is great for just sitting there most of the time unless you really need it. That frees up capital that you'd otherwise tie up in liquid cash that doesn't do anything.
