Anybody from California might be familiar with Trader Joe's. It's a grocery store that sells nothing but non-GMO, no preservative, no chemical food (health food). Most health food stores sell their goods at prices well above the cost of "normal" food, but not Trader Joes. We just got one outside of Houston and a friend of mine kept telling me to go there. He made it sound like they had everything under the sun. Well, I finally took the time to drive out there (1hr) and when I got there I was almost pissed off. I was expecting something the size of Walmart, but it was nestled in a little shopping strip. My opinion was slowly reversed as I toured the store. First thing I noticed was that half of the ~30 people in the store were employees. I kept wondering "whay does a store half the size of Walgreens need more employees than Walmart?" Then I realized why. They really do have just as much food as any other mega-grocery, but they pack it all into this small space. They need a team of stockers to make sure there's always some of everything on the shelves. Where Walmart pays to build and climate control a 5 acre store full of 20ft shelves packed with the exact same item and one guy to stock it all in the middle of the night, Trader Joe's pays a fraction of the price for real estate and employs 10X as many people to keep the place stocked. They do more with less. They do it with less SPACE, as opposed to everybody else, who thinks efficiency is only achieved by less PEOPLE. And some how, despite their "inefficient" business technique, they are able to sell their healthy goods for the price of the food in Walmart, despite paying all these people. and the food is really good. I'm eating a TV dinner right now, on par with home cooking (it is home cooking, frozen) and it was only 3$.
