Because as a modern culture we would rather eat cheap, eat unhealthy and get instant gratification instead of spending time and money on better alternatives. It comes down to our own laziness.
MSG and lots of it
I haven't had bad service at this particular location. Considering my allergy to MSG, it isn't in the basic taco I get, but I can't speak on the rest of the menu. As for why I eat Taco Bell? Simply put... when I am in a hurry, rushing home after a tough day, this is a fast alternative to standing for a couple of hours cooking. No, not as good, but easier and faster. Cheaper and faster than dealing with a restaurant.
