People buy crap. They buy on taste, they buy on price, they buy on marketing. The problem, in fact, is the consumer. Demand will always be filled, and demand is not subject to law.

Here in China, I witnessed a commercial, western-style, pre-packaged apple juice drink yesterday that was sold for 6元 (just under 1USD) for 500mL. On further inspection, it contained 10% 'real' apple juice (which could mean anything...), some artificial flavoring and colouring, glucose syrup, aspartame, and preservatives. They must be making a killing: it was 90% water. Health impact? People used to drink tea - you be the judge.
