Ah, perhaps not.
Bear in mind that this group is a bunch of outliers, as numerous other threads make clear. So to look at her pontifications though the lens of what is common knowledge and practice among the members here would be, I think, misleading and inaccurate.
The group she is addressing is no one on this board, but we've all met the members of that other group. Those are the ones who think "I can make the payments" = "affordable". Savings? They have a few grand at best and that's a minority. They have never in their lives paid cash for a car or a home, new or used. They have a wallet full of credit cards and routinely carry a balance on most if not all of them from month to month.
Those are the folks who don't have a pension, don't have employer-subsidized HI in retirement, and will be living off SS as their sole source of income when they stop working. I think that constitutes most of the working-age population in the U.S., and yeah, if they're able to, they should work until they're 70 or later.
So for that group, Suze is almost certainly dead on.
