Question

is it unethical to design a consumption environment is a way that significantly alters consumer emotions

Answer 1

I think this will be unethical to exploit the emotions of consumers to extract profit. Consumption should be on the basis of rational choice of consumers. It would be unethical because the consumer would not want to be a subject to such a consumption environment which significantly alters consumer emotions. Consumers would like to make informed consumption decisions on the basis of a balanced emotional and mental states. Alter such emotional states will be equal to the unethical exploitation of consumer's emotions to extract business profit.
