The breakdown by income is particularly disturbing to me. No one making over $100k per year has a good excuse for not having $1k in a savings account. No one.

I think you might be confusing "savings account" literally, and $1k in some type of semi-liquid account (or at least, the ability to "come up with" $1k of spending power in an emergency). I am fortunate and make a few hundred thousand a year. I don't keep cash in my savings accounts (other than enough to keep them free) because any real "savings" money goes into real investments like stocks or ETF's. I keep enough in my checkings to cover things I need cash for (rare) and paying many of my bills, but 99% of what I spend goes on my credit card for rewards, and I have plenty of credit to where I wouldn't really need cash today for anything. My cash flow is sufficient where any large charge this statement could be paid in full by the due date without the need for me to liquidate any of my assets. Liquidity and immediate access to cash becomes much less important when you have an established line of credit and good personal cash flow.

Just saying that as someone who makes more than $100k I'm not surprised by that number at all. At least, personally, I'm trying to make my money work as much as it can for me. And it isn't doing that sitting in a savings account. It also doesn't give me the warm fuzzies any more because, really, $1k isn't much of a safety net at the level I'm at, and it doesn't make much sense to park what would be a real, sizable safety net in a low return savings account (because as I said, liquidity doesn't matter as much anyways). Does that make sense?
