Economic systems are not something handed down from God: they are social constructs. If you don’t like $1.2M audio systems, instead of not buying it, change the system that caters to millionaires. You are just being an apologist for laissez faire capitalism nothing more ... Prices today are a reflection of the (passive, like you maybe?) acceptance of the grossly unequal economic structure we have in the U.S. today. It doesn’t have to be that way.
You're being silly because it's essentially impossible for any of us to change our economic system. But given that you're so dissatisfied with it, why do you remain a passive victim to a system you dislike? There are other countries that operate under different systems. Some are democracies, too. It's a big world!
