The image presented shows a person holding a single plastic grocery bag by the handle using only their little finger, commonly called the "pinky." The bag appears to contain a few items, suggesting that it is not very heavy. The person's attire is casual, with a partial view of a t-shirt and cargo shorts.
Superimposed text on the image reads, "BIDENOMICS has made me stronger..." followed by a second line below the bag that adds, "...I can now carry $70 in groceries with just my pinky." This caption is a critical commentary, using sarcasm to express a viewpoint about the purchasing power of money or the cost of groceries, presumably in relation to economic policies during the administration of U.S. President Joe Biden.
The humor in this image comes from the exaggerated claim that $70 can now only buy a small number of groceries, light enough to be lifted with the smallest and usually weakest finger. This hyperbolic statement implies that grocery prices have increased or the value of money has decreased, reducing the quantity of goods that can be purchased.
The joke may also play on the common fitness trope of becoming stronger, but in this case, the "strength" is not physical but the supposed economic resilience developed through coping with increased prices. The irony is that the person is not literally stronger; they are simply able to purchase less with more money, making the weight of their usual groceries lighter.
Another element of humor could be the mismatch between the expectation of BIDENOMICS has made me stronger I can now carry 70 in groceries with just my pinky
