That's sad to hear. I too am a firm believer in capitalism. While there are flaws, its the best we have so far. You mention a lot about commodities and link capitalism with the desire of consumer products. I agree that people do "worship" material goods but reject the idea that this defines capitalism. Instead, capitalism has given us choice and freedom. Technology gives us time which we can utilize as we wish. R&D in areas such as medicine and health help save and improve lives. Consumer goods such as automatic shower cleaners and toilet cleaners help us live cleaner/hygienic lives. I believe a class trip will open their eyes to how lucky they are to be living in America (I'm assuming America - and yes, I am just joking about the trip, I know students probably don't want to fork out thousands of dollars to travel)....I always ended up being the devil's advocate for capitalism
