It is unfortunate that the Church uses the term "consumerism" instead of "materialism".

For me consumerism is a social force designed to aid and protect consumers by applying moral, social, and economic pressure on the society and its institutions to make them responsive to the needs of all consumers, including the marginalized. Consumer well-being includes four parts, (1) goods and services from the marketplace, (2) goods and services from the public sector, (3) responsibility for the natural environment, and advocacy for the well-being of others.

Thanks for the clarification. Perhaps it's a translation issue. When I introduce the term, I'll mention the difference. There's a term for a word that can mean its own opposite -- like "cleave" or "oversight". But my brain can't recall it.
