I've definitely seen what you're describing, but not all of our supermarkets are like that. If you visit higher-end supermarkets (like HEB or Trader Joe), you'll see fresh breads baked in-store, gourmet cheeses, top quality meats, and fresh in-season fruits. If you visit Walmart Supercenter grocery stores, you'll see mostly lower-end crap and frozen boxes. The simple explanation is that each is catering to what their audience expects, and the prices they can afford.
