What makes you think that "consumerism" or "buying a freeze or car" is evil and kills morality in the person?
Do you think if you bought a charkha and started your simple living on it, it will make you moral?
Consumerism is not bad. Atleast government gets sales tax from people who don't even feel income tax. Atleast, part of their "hard-earned" black money goes into building highways and modernising airports.
