It’s not just that, it’s Boomers as a generation not saving.
Obviously some did, but most have lived their entire lives paycheck to paycheck and have zero security net. It’s why they’re not retiring like other generations, it’s not a choice, they just can’t ever stop working.
And they can’t recover from any speed bumps they hit. Losing a spouse for those people also means losing an income. And that can mean losing housing.
