Probably not even just those 2 types. Those who live below their earnings but weren't cash rich nor had to dip into savings (I'd say I come under that category) didn't feel it much, I barely see any change in my outgoings & haven't had to get any help from savings or cut back at all
Like you say, it's common sense, unfortunately not a lot of people seem to have that nowadays as they've been used to splurging when the urge takes them & paying for it later. I know a couple of people in that category, one has aways been in debt but manages to spend money like its going out of fashion, I'm sure he's feeling the pinch now!
