I feel like I am living in a different universe to the author. My beef still costs around $5/lb, my milk is still roughly $3/gal, similar on a lot of staples I buy regularly. My shirts cost about $5 for a t-shirt, and my jeans cost $20 or so. I spend 80% at Costco and 20% at King Soopers (Kroger).
Ancedota I know, but the author is writing like Big Business has 100% coverage of the whole market.
Sincere question: where are you buying beef for $5/lb? I shop at Costco and ground beef is close to $10/lb
Define "beef"? My beef is $20/lb for flank!
The article contains 31 references. Of course, no report on the _general_ market trends are going to cover every anecdote in the US. It could be that the staples you mentioned aren't affected to the same degree. How about your non-staples? How about cars? Houses? Vacation expenses?
In fact, your comment could be read as the exception that proves the rule: you haven't been affected by rising costs because you stick to staples and avoid "frivolous" purchases (that is, you live frugally, as suggested by the article).
