Haven't been to Kroger, or as we used to say, Krogers, for quite a while, but I assume what this means is that much of their floor space is taken up by low-quality prepared food and over-the-counter medicines. But that's true of every large grocery in the US.
I cannot fathom how you've come to this conclusion. I've been to 100 Kroger stores in my life and not one fits your description.
