It's not a scam, just capitalism's supply and demand in motion. Unprocessed food like brown rice always cost more even though it should be cheaper to produce. If people would just eat better healthy food would be cheaper.
People are easily fooled by marketing. They think Snapple is healthy because of marketing campaigns. It's not much different from Kool Aid. When I was a kid the "healthy" drink was Hi C because it was sugar water with a teaspoon of "REAL JUICE!". Now we have sugar water with "NO ARTIFICIAL COLORS OR FLAVORS!"
I admit Ioccasionally down a diet Snapple when I'm out, but when I'm home I just make a pitcher of real iced tea. It takes 5 minutes and it's so much better (and cheaper)
