If people in aggregate are suddenly unable to "afford" things, then you're not talking about inflation. People (again, in aggregate) have more money (not wealth) than they did a few years ago, which is what "inflation" means. On average, it's a rescaling, nothing changes.
Now, individuals may be hurt or helped[1] by this aggregate rescaling. But it remains a rescaling, and if you try to interpret it the way you just did you're going to get your predictions wrong every single time.
[1] FWIW: if you hold a mortage or any other large non-inflation-indexed loan, you should be cheering for inflation to dilute your debt. Most US homeowners are coming out ahead. They don't explain this well on the news networks though.
